Ramesh Reddy resolved TEIID-734.
--------------------------------
Resolution: Done
This exception was happening for two reasons. One Channel handler was throwing a exception
when the channel is closed, even when the client requested it.
Also, the ILogon.ping method was being used with dual purpose.
1) ping for the session instance
2) ping for the server instance, if there is spare server socket instance avaialble to use
by the next connection in the same JVM, if the first connection has been closed and
released the server socket instance to the pool.
In the (2) the ping was inadvertently using the cached session id, thus throwing a
exception, and making the cached instance un-usable. Now, LogonImpl correctly removes the
cached session id when the session logs off, and then if a ping calls comes thorough
without the session id, then it treats that call as server instance ping.
Exception while closing the JDBC Connection to the Teiid Runtime
