See BugDB # 17315456 for detail.

When running java version "1.7.0_17" on OS/X and running jmx enabled cache
server in active persistence mode, causes SIGSEGV in DefaultCacheServer when
connecting from jconsole.

 COUNTER INDICATORS:
 TRIGGERS:
 Attaching to a JMX process via jconsole will cause the crash. Attaching via JMC also
 shows the the coherence process aborting.
 KNOWN WORKAROUND: N/A
 PRESENT SINCE: Seems to be an issue in the jdk7u port of Mac OSX
 HOW TO VERIFY:
 NOTES FOR SE: A testcase is available via BugDB report. I'm seeing some other issues while trying to reproduce the SEGV :

java(417,0x19fdef000) malloc: *** error for object 0x19fdde430: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
cache-server.sh: line 22: 417 Abort trap: 6 $JAVA_HOME/bin/java


There are similar reports of JNI network exception crash/issue already in JIRA.
