causes exception
Key: CONNECTORS-836

Project: ManifoldCF
Issue Type: Bug
Components: Framework crawler agent
Affects Versions: ManifoldCF 1.5
Reporter: Karl Wright
Assignee: Karl Wright

The exception is as follows:
{code}
Exception in thread "Shutdown thread" java.lang.IllegalStateException: Already
have a lock in place:
'/org.apache.manifoldcf.locks-_Cache_JOB_1386770226340/read
-0000000317'; can't also write lock
'/org.apache.manifoldcf.servicelock-AGENT_org.apache.manifoldcf.crawler.system.CrawlerAgent'

It looks a bit like the shutdown thread is somehow inheriting the wrong
lockmanager instance in this case??
