      Description

      It appears that Jikes RVM has a bug in the implementation of its reflection.
      For the detail, look at the patch and the test case: reflection.patch and
      Reflection.java. Try the following.

      1. To see the bug, try the following three command lines.

      $javac ReflectionTest.java

      $java -showversion ReflectionTest
      java version "1.6.0_10"
      Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
      Java HotSpot(TM) Server VM (build 11.0-b15, mixed mode)

      newInstance: pass
      invokeVirtual: pass
      invokeStatic: pass

      $rvm ReflectionTest
      ...
      newInstance: pass
      invokeVirtual: fail
      unexpected cause of the Invocation target exception:
      java.lang.reflect.InvocationTargetException
      ...
      invokeStatic: fail
      unexpected cause of the Invocation target exception:

      2. To correct the bug, try the following.

      • Apply the patch: reflection.patch
      • Build Jikes RVM
      • Run it

      $rvm ReflectionTest
      newInstance: pass
      invokeVirtual: pass
      invokeStatic: pass

          Just FYI, MRP won't apply this patch as it is incorrect.
