Trouble Stopping a threaded OSGi bundle

Hi all,

I am using Equinox to run my OSGi bundle. The bundle runs a thread for indefinite time. At certain point of time, I may need to stop the bundle. The problem I face is that, i am not able to stop the bundle!! When I issue the stop command on the OSGi console.. I get the following error:

org.osgi.framework.BundleException: State change in progress for bundle "file:I:\OSGiRuntime\Equinox\custom\ThreadBundle.jar" by t
hread "main".

Anybody know how to solve this?
