/**
* This class implements the JTA Transaction API for the J2EE RI.
* It is a wrapper over the JTS Transaction object that provides optimized local
* transaction support when a transaction uses zero/one non-XA resource,
* and delegates to JTS otherwise.
* This object can be in two states: local tx (jtsTx==null) or global (JTS) tx.
* If jtsTx!=null, all calls are delegated to jtsTx.
*
* Time out capability is added to the local transactions. This class extends the TimerTask.
* When the transaction needs to be timedout, this schedules with the timer. At the commit
* and rollback time, task will be cancelled. If the transaction is timedout, run() method
* will be called and transaction will be marked for rollback.
