/**
 *
 * This class is useful only for enlist via the JTA API. In particular, this class
 * is a 'workaround' for buggy XAResource implementations where isSameRM returns false
 * even if it should not. With the default automatic resource registration mode,
 * this situation would lead to another XATransactionalResource being added to the
 * configuration for each such enlist. As an alternative, this class pretends to
 * recognize <b>any</b> XAResource and can be used to avoid problems when
 * automatic registration is <b>disabled</b>: instead of reporting errors
 * claiming that the XAResource is unknown for faulty isSameRM cases,
 * this class will silently accept them.
