Hello Peter;

Just anecdotal evidence -- no concrete logs etc... just wanted to see if anybody knew any issues there before I started a more involved investigation.  The new method I am trying is;

    java.util.UUID.randomUUID().toString();

cheers.

I've been using this and haven't had a problem..... yet.
Which cases have you found that it's not unique?
If you find a different method, do you mind posting it here so we can look into it too?
...
The method;

   EOTemporaryGlobalID.assignGloballyUniqueBytes(..)

...has javadoc that reads;

Assigns to uniqueBytes an array of bytes that represent a byte string that's guaranteed to be unique network wide.

In production I believe that I have seen some cases where it might not be completely unique.  Has anybody else come across this sort of problem with the TGID before I start looking at the J2SE equivalent.
