Re: [aspectj-users] CFlowCounter internal error when loading application in tomcat
|
Hi,
That is a funny one...

There is no clinit (static initializer) in ThreadStackFactoryImpl, so
I can't tell what is null.
You aren't accidentally using a woven aspectjrt.jar are you? Do you
have spring insight in the mix? (since that would also be weaving
things). Any other load time weaving going on?
You could try setting this system property for the launch to send the
cflow initialization code down a different route:
aspectj.runtime.cflowstack.usethreadlocal=false
Just to see if that makes a difference.
