  • Doc strings are generated for classes and methods.

  • Complete rewrite of the core module code to deal unattached threads,
    improved hardening, and member management. Massive number of internal
    bugs were identified during the rewrite and corrected.
    See the :doc:ChangeLog-0.7 for details of all changes.

  • API breakage:

    • Java strings conversion behavior has changed. The previous behavior was
      switchable, but only the default convert to Python was working.
      Converting to automatically lead to problems in which is was impossible
      to work with classes like StringBuilder in Java. To convert a Java
      string use str(). Therefore, string conversion is currently selected
      by a switch at the start of the JVM. The default shall be False
      starting in JPype 0.8. New code is encouraged to use the future default
      of False. For the transition period the default will be True with a
      warning if not policy was selected to encourage developers to pick the
      string conversion policy that best applies to their application.

    • Java exceptions are now derived from Python exception. The old wrapper
      types have been removed. Catch the exception with the actual Java
      exception type rather than JException.

    • Undocumented exceptions issued from within JPype have been mapped to the
      corresponding Python exception types such as TypeError and
      ValueError appropriately. Code catching exceptions from previous
      versions should be checked to make sure all exception paths are being

    • Undocumented property import of Java bean pattern get/set accessors was
      removed as the default. It is available with import jpype.beans, but
      its use is discouraged.

  • API rework:

    • JPype factory methods now act as base classes for dynamic
      class trees.
    • Static fields and methods are now available in object
    • Inner classes are now imported with the parent class.
    • jpype.imports works with Python 2.7.
    • Proxies and customizers now use decorators rather than
      exposing internal classes. Existing JProxy code
      still works.
    • Decorator style proxies use @JImplements and @JOverload
      to create proxies from regular classes.
    • Decorator style customizers use @JImplementionFor
    • Module jpype.types was introduced containing only
      the Java type wrappers. Use from jpype.types import * to
      pull in this subset of JPype.
  • synchronized using the Python with statement now works
    for locking of Java objects.

  • Previous bug in initialization of arrays from list has been

  • Added extra verbiage to the to the raised exception when an overloaded
    method could not be matched. It now prints a list of all possible method

  • The following is now DEPRECATED

    • jpype.reflect.* - All class information is available with .class_
    • Unnecessary JException from string now issues a warning.
  • The following is now REMOVED

    • Python thread option for JPypeReferenceQueue. References are always handled with
      with the Java cleanup routine. The undocumented setUsePythonThreadForDaemon()
      has been removed.
    • Undocumented switch to change strings from automatic to manual
      conversion has been removed.
    • Artifical base classes JavaClass and JavaObject have been removed.
    • Undocumented old style customizers have been removed.
    • Many internal jpype symbols have been removed from the namespace to
      prevent leakage of symbols on imports.
  • promoted --install-option to a --global-option as it applies to the build as well
    as install.

  • Added --enable-tracing to to allow for compiling with tracing
    for debugging.

  • Ant is required to build jpype from source, use --ant= with
    to direct to a specific ant.

  • Java reference counting has been converted to use JNI
    PushLocalFrame/PopLocalFrame. Several resource leaks
    were removed.

  • java.lang.Class<>.forName() will now return the java.lang.Class.
    Work arounds for requiring the class loader are no longer needed.
    Customizers now support customization of static members.

  • Support of java.lang.Class<>

  • java.lang.Object().getClass() on Java objects returns a java.lang.Class
    rather than the Python class

  • java.lang.Object().class on Java objects returns the python class
    as do all python objects

  • java.lang.Object.class_ maps to the java statement 'java.lang.Object.class' and
    returns the java.lang.Class<java.lang.object>

  • java.lang.Class supports reflection methods

  • private fields and methods can be accessed via reflection

  • annotations are avaiable via reflection

  • Java objects and arrays will not accept setattr unless the
    attribute corresponds to a java method or field whith
    the exception of private attributes that begin with

  • Added support for automatic conversion of boxed types.

  • Boxed types automatically convert to python primitives.

  • Boxed types automatically convert to java primitives when resolving functions.

  • Functions taking boxed or primitives still resolve based on closest match.

  • Python integer primitives will implicitly match java float and double as per
    Java specification.

  • Added support for try with resources for java.lang.Closeable.
    Use python "with MyJavaResource() as resource:" statement
    to automatically close a resource at the end of a block.
