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
