BeanShell 2.1.0

This release formalizes the merge of 2.0b6 with suitable backports from
the development (HEAD) version of BeanShell (3). Also included are
are some ALv2 contributions to the BeanShell2 fork that had not been
folded into BeanShell but are still applicable to this version. For
backwards compatibility purposes, the 2.x branch of BeanShell still
supports a minimum Java version of 1.6.

2.0b4 Release. May 27, 2005.
Jan 13, 2019
Announcement - BeanShell 2.0b1
------------------------------

After several months of intense work I am pleased to announce the first
beta
release of BeanShell 2.0.  With version 2.0 BeanShell becomes a fully
Java
compatible scripting language.  BeanShell is now capable of interpreting
ordinary Java source and loading .java source files from the class path.
Although this code is still in beta I have been able to execute almost
all of
the 165 example programs from my book (Learning Java, O'Reilly &
Associates)
without modification as well as BeanShell's own ClassBrowser.java file.
The additional code to make this possible adds only about 30K to the
size
of the package and the core minimal language distribution without class
support
remains less than 150K.

BeanShell scripted classes are fully typed and appear to outside Java
code and
via reflective inspection as ordinary classes.  However their
implementation is
fully dynamic and they may include arbitrary BeanShell scripts in their
bodies,
methods, and constructors.  Users may now freely mix loose, unstructured
BeanShell scripts, method closures, and full scripted classes.
BeanShell
scripted classes are "bound" in the script namespace in which they are
declared
and so can freely refer to other scripted items such as scripted
methods,
commands, and "global" variables of the script. e.g.

    // MyScript.bsh
    count = 5;

    class HelloWorld extends Thread {
        public void run() {
           for(i=0; i<count; i++)
              print("Hello World!");
        }
    }

    new HelloWorld().start();

All methods and constructors of the scripted classes delegate to the
BeanShell
interpreter at runtime and all typed variables appear as true class
members.
Loosely typed variables and methods may still be used inside the class
but are
strictly private to the class body.

Previous limitations on the implementation of anonymous inner classes
have also
been lifted, allowing BeanShell to extend arbitrary Java classes and
implement
abstract base classes.

BeanShell 2.0 also brings with it two new language features:

JDK 1.5 style static class imports.  You can import the static methods
and
fields of a java Class into a BeanShell namespace. e.g.

    static import java.lang.Math.*;
    sqrt(4.0);

Instance object imports (mix-ins) with the importObject() command.  You
can
import the methods and fields of a Java object instance into a BeanShell
namespace.  e.g.

    Map map = new HashMap();
    importObject( map );
    put("foo", "bar");
    print( get("foo") ); // "bar"

1.0

Changes from 0.96 to 1.0
Not necessarily in order of importance

    Added generalized support for scripts implementing interfaces (e.g.
arbitrary event listeners). This uses the important new JDK1.3
reflection proxy mechanism to manufacture a proxy interface at run time.
No code generation is necessary!
        Added support to the cast operation to use the new mechanism.
        Added support for automatic conversion to interface on method
selection. e.g. if you attempt to pass a bsh scripted object as a method
argument where the method signature calls for an interface an automatic
cast to the appropriate interface type will be attempted.
        Added a magic method invoke(method,args) which can be used to
handle method invocations on undefined interface methods in bsh objects.
This takes the place of "dummy" adapters; allowing a script to ignore
one or more methods of an interface that it is implementing. Note: one
special case - direct invocations within scope (e.g. command
invocations) are not currently sent to invoke.
    Added startup file (.rc file) support. Bsh will source the file
"user.home"/.bshrc upon startup. This defaults to C:\Windows under win98
and $HOME under Unix. (can the home be set with an env var under Win?
"home" doesn't seem to do it).
    Added arguments to file invocation on command line. e.g.

     java bsh.Interpreter MyClass foo bar

    Args are accessible through the root bsh object: String [] bsh.args
    Enhancements to JConsole submitted by Daniel Leuck; Added color and
image support, fixed several bugs.
    Added support for inner classes. This should all work as expected,
but it's new so let me know if you find weirdness.
        Added support for inner classes to import statement.
    Changed the way eval()/source() handle script errors. Instead of
returning the error object as a value it is now wrapped up with some
context and rethrown as an EvalError. So you can simply catch the error
with a normal try/catch block if you want to. Previously errors in
sourced/eval'd files were being squelched. This was bad. Note:
exceptions generated by the script or through code called by the script
are thrown as TargetErrors (a subclass of EvalError) which can also be
caught and examined.
    Improved error reporting in many areas. Fixed really annoying error
reporting bug that squelched target error info in sourced files (and
commands).
    Improved bsh cast operation so that it throws standard
ClassCastException for invalid cast. You can now guard against them with
the ordinary try/catch in a bsh script.
    Modified the command line portion of the grammar to accept arbitrary
expressions. e.g. you can type ``5*2;'' or ``foo instanceof Foo;'' on
the command line now without any enclosing parens. (Of course you won't
see anything unless you're using the show() option).
    Removed the old AWT version of the GUI console. If you need it you
can get it on the web site separately. I may reconsider this.
    Removed the console() command which was primarily for the old AWT
console.
    Modified the browseClass() command to take an object instead of a
string class name. Now you can simple say browseClass( someObject ) and
pop up the class browser to the correct place. Special hack: If the
specified object is a Class it will use the class. This will all
probably be replaced by a general browse() method for the upcoming
object inspector.
    Changed the return type of the frame() command to allow it to return
an internal frame when desktop is active. Frame will now do the correct
thing whether the desktop is up or not.
    Rebuilt the distribution with JavaCC / JJTree version 1.1. Haven't
notice any difference yet.
    Fixed the 'for' scoping bug - See docs on for scoping for
clarification. Previously variables declared within the for-init section
were leaking out into the outer namespace.
    Fixed a bug in which tokenizer errors would cause the interpreter to
hang or exit. They are now handled like other parsing errors. In the
future we may want to break them out so that they can be handled
separately from EvalError.
    Added missing += form of string concatenation.
    Incorporated a patch and test suite case from Roger Bolsius that
corrects some of the package / hidden reflected class access. Previously
the code did not handle the more difficult cases.
    Incorporated a patch from Mike Woolley which works around JDK bug
4071281 (EOF problem) under Windows JDK v1.1.
    Fixed most of the bugs in server mode. Run the server pair (httpd /
sessiond) using the server( port ) command. Then you can telnet to
port+1 or attach your web browser to port. Note that the web browser
must support swing to run the remote JConsole. We could supply the
AWTConsole back for compatability with old browsers... but I'd like to
move on.
    Internal trivia - changed the prefix of the names of all of the
parser node classes from AST to BSH.
    Fixed a bug which caused ClassCastException during (ironically) a
bsh cast operation.
    Improved the test harness slightly and added a number of new files
to the test suite for all of the new features. Please send more test
cases for the test suite!
    Internal change: Simplified the code that determines array base
types.
    Fixed bug where special characters on input (e.g. control charcters
^D) would cause the tokenizer to loop on errors. Non printable chars are
now skipped as white space.
    Added the missing do-while statement
    Internal: Tightened up the code a bit by combining the BSH node
conditional evaluation into one place.
    Fixed some race conditions in the JConsole. Fixed multi-writer
console problems.
    Fixed order of evaluation bugs: classes now always first, then bsh
vars. Note: this may not always be desireable. e.g. if you have a class
named "x" in your path (violating the common naming conventions) then
you can't use a variable of name 'x' in your scripts. Conversely though,
it prevents one from doing "Integer = 5;" and shadowing the
java.lang.Integer class with a variable name. Any thoughts on this?
    Corrected handling of the bsh root object.
    Added a menu item to console to redirect stdin/stdout/stderr. If you
close the console they are restored to the original System.in,out,err.

BeanShell 2.0b6 is a security update that is functionally equivalent to the previous version 2.0b5.

No other functionality has changed since 2.0b5, but this is a recommended update for all BeanShell users, as it fixes a remote code execution vulnerability.

Security fix (CVE-2016-2510)

This release fixes a remote code execution vulnerability that was identified in BeanShell by Alvaro Muñoz and Christian Schneider. The BeanShell team would like to thank them for their help and contributions to this fix!

An application that includes BeanShell on the classpath may be vulnerable if another part of the application uses Java serialization or XStream to deserialize data from an untrusted source.

A vulnerable application could be exploited for remote code execution, including executing arbitrary shell commands.

This update fixes the vulnerability in BeanShell, but it is worth noting that applications doing such deserialization might still be insecure through other libraries. It is recommended that application developers take further measures such as using a restricted class loader when deserializing. See notes on Java serialization security, XStream security and How to secure deserialization from untrusted input without using encryption or sealing.

A MITRE CVE number has been reserved: CVE-2016-2510

To execute the Beanshell user interface, either double-click the JAR file, or run it with:

java -jar bsh-2.0b6.jar 

You will need Java 5 or later installed. Note that there is a bug (#4) which may cause a hang, preventing the user interface from running with Java 8.
