JVM Crashes when trying to getMagicNumber

Yogender Nerella 26 August 2006 05:59:03
 Hi,

We are running jgroups in JNI environment and in some
cases, JVM is crashing with the following stack on
SunOS JDK 1.5_06 version.

I am using Jgroups2.3 on SunOS Qasolaris4 5.10 Generic
sun4u sparc SUNW,Sun-Fire-V440.­

JDK Version:
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition
(build 1.5.0_06-b05)
Java HotSpot(TM) Server VM (build 1.5.0_06-b05, mixed
mode)


TIA
Yogi

 Looks like a VM bug to me. Can you set a breakpoint into

org.jgroups.conf.Cl­assConfigurator.getM­agicNumber(java.lang­.Class)
bci:5 line:153 (Compile

and debug this ? Also make sure you have jg-magic-map.xml in your classpath

 Bela,

I have jgroups-all.jar in my classpath which should
take care of jg-magic-map.xml right?

I have a question on RpcDispatcher, if I invoke a
remote method and the request has to be handled by all
the members, on what thread the requested method will
be executed. I thought the requesting thread and
processing thead will be different. Can you take a
look at the following stack and let me know why is
this happening?

Thanks
Yogi

If you set incoming use_incoming_packet­_handler=true, then it will run
on the incoming packet handler's thread, otherwise on the multicast
receiver's thread. This is slightly different if you use TCP. Note that
this will change with the threadless stack
(http://jira.jboss.­com/jira/browse/JGRP­-181).

This is the case, yes

Hmm, it looks as if java.lang.AbstractS­tringBuilder.expandC­apacity()
core dumps. This is in user code
(com.peregrine.sc.r­esource.SCTaskDispat­cher.process()), so why don't you
try to isolate this and see whether you can reproduce it ? Doesn't look
like a JGroups problem...
