jruby -S irb broken on solaris in 1.7.16 with JDK 7

[mulvaney]

jruby -S irb throws missing file errors in 1.7.16 using Java 7. It works ok with Java 8, and it worked fine in 1.7.15 with both Java 7 and Java8.

$ java -version
java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)
$ jruby-1.7.16/bin/jruby -S irb
irb(main):001:0>

$ java -version
java version "1.7.0_67"

Java HotSpot(TM) Server VM (build 24.65-b04, mixed mode)
$ jruby-1.7.15/bin/jruby -S irb
irb(main):001:0>

But the same thing fails in 1.7.16:

$ java -version

I have seen such an error before somewhere.

what LANG or LC_ALL or locale do have on that machine of yours ?

[mulvaney]

I don't have LANG or LC_ALL set. I should point out that I get this error a lot, about all kinds of different files. irb was just an easy way to show it. For example:

$ ./jruby-1.7.16/bin/jruby -S gem environment
Errno::ENOENT: No such file or directory - /home/mm5830/.gem/jruby/1.9
          file? at org/jruby/RubyFileTest.java:131
           dirs at /home/mm5830/jruby-download/jruby-1.7.16/lib/ruby/shared/rubygems/defaults/jruby.rb:83
        collect at org/jruby/RubyArray.java:2407
           dirs at /home/mm5830/jruby-download/jruby-1.7.16/lib/ruby/shared/rubygems/defaults/jruby.rb:82

I don't have a ~/.gem/jruby/1.9 directory. I do have ~/.gem/jruby/1.9.3, though. RubyFileTest is checking to see if a file exists on line 131; it shouldn't be throwing a ENOENT if the file doesn't exist, it should be returning the empty file spec but apparently it is not.

If I change JAVA_HOME to point to Java 8, then I get:

$ ./jruby-1.7.16/bin/jruby -S gem environment

My path still says java1.7 but I don't think that matters, jruby appears to care about JAVA_HOME but not which java is executable in the path.

JRuby also breaks for me if I don't have the ~/.gem/jruby/1.9 directory (OS X 10.9.5):

Creating the directory fixes Rubygems in JRuby.

@mulvaney could you verify that it also fixed on solaris ?

https://oss.sonatype.org/content/repositories/snapshots/org/jruby/jruby-complete/1.7.17-SNAPSHOT/jruby-complete-1.7.17-20141202.175858-1.jar

[headius]

I'm going to proactively resolve this. @mulvaney please let us know if it's not fixed on Solaris.
