Running hotspot with valgrind to detect memory leak?

[Sandeep Konchady]

Hi,

    Extending what Neo Jia ran on JVM, I tested OpenJDK VM with Valgrind 
using MemoryMonitor demo. To my surprise I got a HotSpot crash in 
nmethod.cpp. I am attaching hs_err log file to this email and can give 
the Valgrind log if needed. Also I was unable to find similar report on 
SDN bug database.

#  Internal Error (nmethod.cpp:1822), pid=6946, tid=80788368
#  Error: guarantee(cont_offset != 0,"unhandled implicit exception in 
compiled code")

Thanks,
Sandeep
