Problem summary
Under some circumstances, the VM debug local mapper code incorrectly handles cases where the method has a large number of local variables.This can cause problems for GC. This can only occur when debugging Java code that includes methods with more than 32 locals.
Problem conclusion
The JVM debug local mapper code has been fixed to correctly identify object slots in all cases. . This APAR will be fixed in the following Java Releases: 7 R1 SR3 FP30 (7.1.3.30) 8 SR2 FP10 (8.0.2.10) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
