The problem sounds like the JreMemoryLeakPreventionListener. In
$CATALINA_HOME/conf/server.xml add appContextProtection="false" to that
Listener:
<Listener
className="org.apache.catalina.core.JreMemoryLeakPreventionListener"
appContextProtection="false" />
You will be opening up Tomcat to a memory leak, which will require
restarting Tomcat when you change your WAR file.
For more on this issue, see this Tomcat thread: http://bit.ly/1bwiKuM and
the Tomcat list for more info.
