Error description
Error Message: A Java application running on Java 5, Java 6 or Java 6.0.1 could appear to hang while 90% to 100% of CPU time is spent in the JIT compiler. A system core dump shows that the JIT compilation thread is executing a deeply self-recursive function named "findCallNodeInTree". . Stack Trace: findCallNodeInTree findCallNodeInTree . . . findSimpleCallReference TR_TransformInlinedFunction::transformReturn TR_TransformInlinedFunction::transformNode TR_TransformInlinedFunction::transform TR_InlinerBase::inlineCallSite .
Local fix
This issue can be worked around using the -Xjit:disableInlining option. Note however that this will cause severe performance degradation.
Problem summary
The inliner algorithm in the JIT compiler can, in some cases, incorrectly enter an infinite self-recursion.
Problem conclusion
This defect will be fixed in: 5.0.0 SR13 6.0.0 SR10 6.0.1 SR1 . The inliner has been updated to avoid the infinite recursion. . To obtain the fix: Install build 20110531 or later
