the class XAResourceRecord method getNewXAResource.

/**
 * This routine finds the new XAResource for the transaction that used the
 * old resource we couldn't serialize. It does this by looking up the
 * XARecoveryModule in the recovery manager and asking it for the
 * XAResource. The recovery manager will then look through its list of
 * registered XARecoveryResource implementations for the appropriate
 * instance. If the XARecoveryModule hasn't been initialised yet then this
 * routine will fail, but on the next scan it should work.
