Mark Little commented on JBTM-1337:

Node names cannot be guaranteed to be unique. Please do not change the way Uid is created, because if they're incorrectly created the whole system comes crashing down.

> Node name is going to give us guaranteed uniqueness for transaction managers, we could use node name instead of hostname and pid.
> Uid is generic, xa node name is part of XA, but they are both in ArjunaCore/arjuna/ so it should not pose any dependency issues.
