APAR status
Closed as program error.
Error description
Error Message: Segmentation error, or UnsatisfiedLinkError. . Stack Trace: The innermost stack frame is interpreted, and it belongs to a method whose name begins with invokeExact_thunkArchetype, declared on a subclass of MethodHandle in package java.lang.invoke. .
Local fix
This issue can be avoided by passing -Xjit:disableEscapeAnalysis. This option may degrade performance, but it can be limited to the problematic method.
Problem summary
In order to reduce the likelihood that a stack-allocated object will have to be moved to the heap, escape analysis devirtualizes calls where the object would escape. This devirtualization could be mistakenly applied to MethodHandle calls.
Problem conclusion
Escape analysis has been modified so that it no longer attempts to devirtualize MethodHandle calls. . This APAR will be fixed in the following Java Releases: 8 SR4 FP7 (8.0.4.7) 7 R1 SR4 FP10 (7.1.4.10) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
