Debug Issue

Java ™ Virtual Machine Tool Interface (JVM TI) breakpoints are reliable only when either the Parallel Scavenge garbage collector ( -XX:+UseParallelGC) or the Parallel Compacting garbage collector ( -XX:+UseParallelOldGC) is used.

When other collectors are used, breakpoints may stop functioning, and JVM TI object tags may become unusable after a full GC operation is performed. Java ™ Debug Interface (JDI) ThreadReferences have an embedded thread ID that depends on JVM TI object tags, thus the embedded thread ID may change unexpectedly. This may cause confusion in thread based JDI events.

Note that the Serial garbage collector ( -XX:+UseSerialGC) is vulnerable to this problem and is selected by default on some platforms. The work around is to explicitly select the Parallel Scavenge collector using the command line option -XX:+UseParallelGC.

(Refer to 6862295.)
