That's not important, IMHO. Problem is in pool's lock, not
XMLFileModule's lock.
Are you sure?
90% sure. Have a look:

Why would getProcessingPipeline() block in the soft pool?
The only challenge here is to find source of
org.apache.avalon.excalibur.component.PoolableComponentHandler, version
excalibur-pool-1.2.jar. Which is not even in archive :(
