> This change simplifies the code that grows the jmethodID cache in > InstanceKlass. Instead of lazily, when there's a rare request for a > jmethodID for an obsolete method, the jmethodID cache is grown during the > RedefineClasses safepoint. The InstanceKlass's jmethodID cache is lazily > allocated when there's a jmethodID allocated, so not every InstanceKlass has > a cache, but the growth now only happens in a safepoint. This code will > become racy with the potential change for deallocating jmethodIDs. > > Tested with tier1-4, vmTestbase/nsk/jvmti java/lang/instrument tests (in case > they're not in tier1-4).
