Re: [Wrapper-user] java.lang.IllegalThreadStateException

[Leif M. <le...@ta...>]

Neeraja,
I did some research on this tonight.  Everything in the wrapper looks 
correct.  But the
wrapper is barfing when it attempts to call System.exit.  This should be 
a valid operation
so this seems like a JVM bug?

Does this look like it applies to what you are seeing?

 From your trace, the Wrapper is calling shutdownJVM from within the 
main command
loop.  That is triggered by the ServiceManager attempting to stop the 
service.  For this
reason, this method should be getting called before the JVM's shutdown 
hooks have
been started.  The call to System.exit within this method should be 
starting the shutdown
hooks it self, but that operation is failing.

This happens after the WrapperListener.stop method has been called.  
However,
because you are using the WrapperSimpleApp helper class, that listener 
does nothing.

I'll give this some more thought, but I don't see how the Wrapper could 
be causing
this on its own...

What happens if you use the 3.2.1 release?  (Shouldn't make any difference)

How about different JVM versions?

Cheers,
Leif
