APAR status
Closed as program error.
Error description
Error Message: ** ASSERTION FAILED ** at ./MarkingSchemeRootMarker.cpp: ((MM_StackSlotValidator(MM_StackSlotValidator::NOT_ON_HEAP, object, stackLocation, walkState).validate(_env))) Invalid class pointer in stack allocated object . Stack Trace: N/A .
Local fix
-Xjit:disableEscapeAnalysis
Problem summary
When the JIT compiler is using the Escape Analysis optimization to stack allocate objects, it potentially may not allocate them according to the required alignment when using a heap larger than 32GB.
Problem conclusion
The JIT compiler has been updated to enforce proper alignment for object allocation regardless of the heap size. . This APAR will be fixed in the following Java Releases: 8 SR3 (8.0.3.0) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
