TODO list

Project
1. add a build file
 - either ant or gant (preferred, hope it's not too complex)

2. generate GroovyDoc in the build

3. do a simple benchmark and profiling


Application
 - fix close and autoclose, do not close if there is running listener
 - implement a JMSPool


Dependency

1. Remove Jencks source code from this project

Refactoring Plan
 - the hierarchy of JMS and JMSPool
 - store connection and session in a JMS, store the JMS in threadlocal; use of JMSCategory will trigger a creation of
   JMS instance in the threadlocal
 - a JMS act as a container that have a start, stop lifecycle
