"WebappClassLoader: Lifecycle error : CL stopped" -- LogManager issue?

[pacow <pe...@justgive.org>]

every once in a while when i run my axis client (which i use in conjunction
with xmlsec)
in the context of my web app, i get the following error as the client attempts
to add the
digital signature:

> WebappClassLoader: Lifecycle error : CL stopped
> org.apache.xml.security.signature.XMLSignatureException:
> The requested algorithm SHA1WithRSAEncryption does not exist.
> Original Message was: class configured for Signature(provider: BC)cannot be found.
>

So something is destroying the ClassLoader?  How do I deal with this? There is
some evidence that it
may be related to the LogManager or something.  Any advice would be greatly
appreciated. Also,
it is worth noting that when I run a client from the command line I never
experience this error.
