The web application [server] created a ThreadLocal with key of type
[java.lang.ThreadLocal] (value [java.lang.ThreadLocal@7436b893]) and a
value of type [net.sf.saxon.expr.sort.LRUCache] (value
[net.sf.saxon.expr.sort.LRUCache@2f0f7240]) but failed to remove it when
the web application was stopped. Threads are going to be renewed over time
to try and avoid a probable memory leak.
