      Description

      My code fails midway through identical iterations with a NativeException:
      java.lang.ClassNotFoundException. The code repeats the same thing over and
      over.
      Code works fine if all is in one file, however it fails towards the 50th
      iteration if it's included from another file (which iteration exactly
      changes each time, but so far in the range 48 to 56)

      1. Case 1: jruby ./integration-test.rb -> All fine [Prints out numbers from
        1 to 100]
      1. Case 2: jruby ./integration-test-2files.rb ->

      NativeException: java.lang.ClassNotFoundException [Prints out numbers from
      1 to 52, then spews out a
      java/lang/ClassLoader.java:373:in `findClass':
      java.lang.ClassNotFoundException: com.xxx.yyy.zzz.ttt.GGClassName
      (NativeException)
      from java/lang/ClassLoader.java:321:in `loadClass'
      from java/lang/ClassLoader.java:266:in `loadClass'
      from java/lang/Class.java:-2:in `forName0'
      from java/lang/Class.java:264:in `forName'
      from java/io/ObjectInputStream.java:621:in `resolveClass'
      from java/io/ObjectInputStream.java:1592:in `readNonProxyDesc'
      from java/io/ObjectInputStream.java:1513:in `readClassDesc'

      The error message is slightly different with jruby 1.7.0RC2
      LoadError: load error: integration-test – java.lang.ClassNotFoundException:
      xxx.yyy.zzz.ttt.GGClassName
      require at org/jruby/RubyKernel.java:1019

      As subsequent test:
      Note: jruby -X-C systematically fails, on both files [All 3 versions tested, error message varies, but always a ClassNotFound error]
      jruby -X+C always works, on both files. [All 3 versions tested]
