-----------------------------------
I have disabled the session serialisation in mifos war.
The huge part of the SEVERE message was due to ThreadLocal variable of
HibernateUtil.
some SEVERE message are still there due to some not-destroyed Threads

INFO: Stopping service Catalina

SEVERE: The web application [/mifos] appears to have started a thread named
[Thread-2] but has failed to stop it. This is very likely to create a memory
leak.

But this really doesn't matter are shutting down the tomcat as you are killing
the JVM, so according to message, "This is very *likely* to create a memory
leak" doesn't mean that it will (or must) cause memory leak.
I do think this severe message is confusing but people have been discussing
this on tomcat's forum too.
http://www.mail-archive.com/[email protected]/msg83407.html
And there is bug in Tomcat bug tracker to make this SEVERE message WARN or INFO.
https://issues.apache.org/bugzilla/show_bug.cgi?id=50175
So, I would close this issue considering that it is an issue with Tomcat as
these messages should not be there if we are killing the Tomcat JVM
