Error description
Error Message: A dump event "traceassert" is received. The snap trace file show the following message: ASSERTION FAILED at sunvmi.c:498: ((accessClass) != NULL) . Stack Trace: This is the native stack trace: j9dump_create () from libj9prt26.so doSystemDump () from libj9dmp26.so j9sig_protect () from libj9prt26.so runDumpFunction () from libj9dmp26.so runDumpAgent () from libj9dmp26.so triggerDumpAgents () from libj9dmp26.so twAssertion () from libj9trc26.so utsTraceV () from libj9ute26.so j9Trace () from libj9trc26.so getClassContextIterator () from libjclse7b_26.so walkFrame () from libj9vm26.so walkStackFrames () from libj9vm26.so JVM_GetClassContext () from libjclse7b_26.so The Java stack trace will be similar to: at java/lang/SecurityManager.getClassContext at Helper.<clinit> at java/lang/J9VMInternals.initializeImpl at java/lang/J9VMInternals.initialize at java/lang/invoke/MethodHandle.lookupMethod at java/lang/invoke/MethodHandle.finishMethodInitialization at java/lang/invoke/DirectHandle.<init> at java/lang/invoke/MethodHandles$Lookup.findStatic . This only affects Java 7
Local fix
Ensure that classes that call getClassContext() in <clinit> have been initialized prior to attempting to look up MethodHandles for their methods or fields.
Problem summary
The problem is due to an invalid assumption regarding when SecurityManager.getClassContext() can be called while looking up a java.lang.invoke.MethodHandle.
Problem conclusion
This defect will be fixed in: 7.0.0 SR4 . The JVM has been changed to only validate the assumption in the correct code path.
Temporary fix
