Claus Ibsen commented on CAMEL-20769:
-------------------------------------
Okay if I do some dirty thread hacking I can maybe simulate that camel-jms
cannot create a temporary queue due to JMS broker failure, and it keeps
looping. And then at the same timer the JMS producer is waiting for that reply
to queue to be ready. However it uses some old thread await that never gets
signalled due to that endless exception. And then in fact we have code
afterwards that has a 10 sec timeout waiting for reply to be ready.
