Hello,
Here are the results:
Code in the MessageReceiver:
<code>
log1.debug("Loading " + url); //$NON-NLS-1$
log1.debug("AgentPlatformServiceMessageReceiverInOut: " //$NON-NLS-1$
+ getClass().getClassLoader().toString());
log1.debug("Digester: " //$NON-NLS-1$
+ new Digester().getClass().getClassLoader().toString());
log1.debug("CatalogBase: " //$NON-NLS-1$
+ new CatalogBase().getClass()
.getClassLoader()
.toString());
log1.debug("MessageReceiver CL == Digester CL? " //$NON-NLS-1$
+ (getClass().getClassLoader() == new Digester().getClass()
.getClassLoader() ? "true" : "false")); //$NON-NLS-1$//$NON-NLS-2$
configParser.parse(url);
</code>
Output:
[DEBUG] Loading

As for the trace of the VM, aparently both classes from commons-chain
and commons-digester are loaded before the exception:

Any idea?
