Local fix
Problem summary
When an event occurs that causes the JIT code cache to be discarded (for example, due to a JVMTI breakpoint), the associated trampoline data is not cleared as it should be. This causes an invalid jump into the code cache.
Problem conclusion
The VM has been updated to also clear the JIT trampoline data when the code cache is cleared. . This APAR will be fixed in the following Java Releases: 6 R1 SR8 FP20 (6.1.8.20) 7 R1 SR3 FP30 (7.1.3.30) 8 SR2 FP10 (8.0.2.10) .
