Master Node running but when i start Slave node the Master Node start

take this issue up with oracle as well following is there response:
***Oracle Support***
Hi,
1) No sure why its running fine master node and facing issue with slave
node.
Since the error getting triggered from the MQ code, I cannot comment much
on the same. Please let me know whether you checked with your application
team.
What's their comment regarding the exception reported? Please keep me
posted . Thank you.
2) I have gone through the Server log provided on this Service request and
verified the case.
As per the log, the EJB exception caused due to the Null pointer exception,
which getting triggered from the MQ code. Suggest you to check with the
application regarding the same.
java.lang.NullPointerException
at org.apache.activemq.TransactionContext.setXid

Looks like it’s this bit of code that is causing the null pointer. I’ve
tracked down the full stack trace which indicates the line highlighted
below, this.connection must be null. This is all ActiveMQ internals though,
nothing custom with application.
private void setXid(Xid xid) throws XAException {
try {
this.connection.checkClosedOrFailed();
this.connection.ensureConnectionInfoSent();
} catch (JMSException e) {
disassociate();
throw toXAException(e);
