[equinox-dev] StackOverflow error while deploying osgi runtime in WAS 6.1 with java2 security

Hi,

I was trying to get my OSGI runtime up and running in the IBM WAS 6.1
. My application is a webapp that uses the BridgeServlet as the
connector between appserver and the OSGI environment. It works fine
untill I enable the JAVA2 sercurity.  Since the error traces are
relevant to the OSGI system bundle, I think you guys have a better
idea what is happening.


In the bundleContextImpl class , the startActivator method calls a
doPriviledged method and it recursively calls the other bundles in the
configured system. This is the expected behaviour i guess. But somehow
it throws a stackoverflow (pasted below) exception while doing that it
seems.

The error I'm getting is similar to the error listed in a eclipse
forum [1] . Their advice is to set the ' eclipse.security = true ' in
the config.ini . I did that and it didnt work for me. Apart from that
I cant see the rationale behind setting that property ; didnt see a
usage of that property  during my debugging session.

any thoughts ? explanations ? welcome.


my environment :

windows XP,
IBM WAS 6.1.29 trial version
equinox runtime 3.5  - (this is bit old, but i cant change this right now)
enabled java2 security
granted all permission to my web-app in the policy file
