Error description

  • Error Message: The Java JIT compiler crashes while compiling the
    method java/lang/ClassLoader.defineClass.
    .
    Stack Trace: TR_TreeTop::getNode
    TR_ByteCodeIteratorWithState<TR_Node*,
    TR_Block>::genPartialInliningCallBack
    TR_ByteCodeIlGenerator::genIf
    TR_ByteCodeIlGenerator::walker

    .
    

Local fix

  • This problem can be avoided with the JVM option
    -Xjit:disablePartialInlining.
    

Problem summary

  • The problem is caused by inconsistent updates by the JIT
    compiler to data about a method call while considering the call
    for partial inlining.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR4 FP2
    .
    The JIT compiler has been updated to be more conservative when
    collecting data about partial inlining candidates.
    

Temporary fix
