Native exception occurs when using scheduler mbean during sh

[robfinner]

Hi,

I'm running JBoss-3.0.1RC1 on Win2K using Sun j2sdk1.4.0 Java Hotspot client VM (1.4.0-b92 mixed mode.)

I have a class that implements org.jboss.varia.scheduler.Schedulable and is configured as follows:


true
com.digitalskyscrapers.crsguides.utils.SchedulableHeartBeat
Schedulabe Test,0
java.lang.String,int
1
60000
-1


It appears that the scheduler did not unhook the system level timer event and that the JVM is not smart enough to do it for the application anyway before it (the JVM) shuts down. Is there some way to fix the scheduler service to listen to JMX shutdown events and then to cancel the timer events before JVM shutdown?

Note that the exception only occurs on about 40% of my shutdowns.

Thanks in Advance!!!!

BTW: My apps seem to run a lot faster under 3.0.1 as compared to 2.4.4. Great job JBoss Team!

What exception are you getting?

From a quick glance, the scheduler should be stopping the timer.

Here's the exception report, but it is not much help. (Please note that I could not find the hs_err_pid1008.log file that was supposedly generated by the JVM)

Hi,

This is a VM error.
The log file is probably in jboss\bin, but it will
just look like the information you posted.

Adrian
