the class InvocationDispatcher method sendSentinel.

private final void sendSentinel(long txnId, long initiatorHSId, long ciHandle, long connectionId, boolean forReplay) {
    //The only field that is relevant is txnid, and forReplay.
    MultiPartitionParticipantMessage mppm = new MultiPartitionParticipantMessage(m_siteId, initiatorHSId, txnId, ciHandle, connectionId, // isReadOnly
    false, // isForReplay
    forReplay);
