Title Body

I configured tomcat to work with a different external open source. However, after the tomcat is running for a few minutes I get: SEVERE: The web application [/MyProject] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@1b3f02f]) and a value of type [org.apache.axis.MessageContext] (value [org.apache.axis.MessageContext@5dbd4e]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak. What could cause it? Where do I have to look? Could it be datapooling on Tomcat? And what does it mean Threads in Tomcat? EDITED Here is my full trace. The application seems to reloads its context while it's still running - and I don't know why!
