--------------------------------

i got the same error. (perhaps an issue with hot-deployment...!?)

>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: ClassLoading

> Occasionally, I will get the exception below when trying to load the bouncy castle library. One would think it is a problem in BC, except for the fact that the NPE is clearly coming from JBoss's RepositoryClassLoader.
> The hard part about this bug is that it happens some of the time and not other times. It's been impossible to reliably reproduce. Restarting the appserver/jvm causes the problem to go away and everything works just fine, but eventually it will happen again. 
> BC is being started in a @Service Bean. The start() method looks like this:
> 	public void start() throws Exception
> 	{
> 		Security.addProvider(new BouncyCastleProvider());
> 	}
> Has anyone else seen this problem?
