Summary: JMSMessageID generation inadequate

Initial Comment:
The current implementation of JMSMessageID generation 

simply uses a randomly generated long no. 

This is inadequate, due to the potential for collisions, 

and should be fixed.



Possible solutions are discussed in this thread:

Fixed in CVS. Will be available in the 0.7.6 release.

Initial version checked in, using a modified version of Tyrex's 

UUID generator. The node identifier portion of the UUID is 

randomly generated - this could be changed to be derived 

from the InetAddress (MD5 encoded?) if it can be determined.



This change has required modifications to the db schema. 

Migration work still needs to be done.
