Hi Clinton and team.

I found an interesting issue.
In case of hot deploy
ThreadLocal localSqlMapSession causes a memory leak.

As you know, iBatis calls getLocalSqlMapSession().close();
but WAS classLoader remains in the memory after a hot deployment
because classLoader still has a reference of the ThreadLocal.

It needs to explictly set null
I tried to test with the code below and it works fine.

getLocalSqlMapSession().set(null);

I hope to improve iBatis
Otherwise iBatis works greate !
Cheers !
