Hi,

I am using jbpm 5.2, tomcat 6, MySql database with BTM transaction manager in Linux (Ubuntu) machine.

I am getting the below issue on tomcat shutdown. it seems like Jbpm-Console is starting some threads and those threads can not be stopped correctly on tomcat shutdow. It results to taking all my CPU memory.

SEVERE: The web application [/gwt-console] appears to have started a thread named [com.google.inject.internal.Finalizer] but has failed to stop it. This is very likely to create a memory leak.

SEVERE: The web application [/gwt-console] appears to have started a thread named [Thread-7] but has failed to stop it. This is very likely to create a memory leak.

SEVERE: The web application [/gwt-console] created a ThreadLocal with key of type [com.google.inject.InjectorImpl$1] (value [com.google.inject.InjectorImpl$1 at 1f957352]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@cc61cb1]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
