RE: openjms "receiver hang" problem

What you're seeing is probably related to the following
bug:
http://sourceforge.net/tracker/index.php?func=detail&aid=1214292&group_id=54
559&atid=474136

This has been fixed in CVS. In 0.7.7-alpha-1 you can increase
the no. of ORB threads to reduce the likelihood of it occurring.
To do this set the maxThreads attribute of TcpConfiguration in openjms.xml:
E.g:
  <TcpConfiguration port="3035" maxThreads="100"/>
