Bela Ban commented on JGRP-1260:
--------------------------------
This is weird, it means that UUID.cache is null. However, UUID.cache is created and
initialized in a static {} initializer, which cannot fail as I'm catching Throwable !
How do you reproduce this ?

------------------------------------
Well, it doesn't happen when developing, just in production :) as usual...
There isn't any fancy classloader involved only the JVM classloader. I have another
one "Cannot send message to null"(I will create another ticket for this one) and
I hope I will have time next week to try to reproduce both of this.

Bela Ban commented on JGRP-1260:
--------------------------------
I have absolutely no idea how this could happen !
We have
static final Cache cache;
static {
cache=...;
}
Then, in UUID.toString() or UUID.get():
cache.get(...);
At this point, static variable 'cache' must be intialized as the static context is
(1) initialized when the UUID class is loaded and (b) this initialization is synchronized
!
A use case would be highly appreciated.
Perhaps this is one of the dreaded classloader issue ? Are you running multiple instances
in different classloaders ? But even then, 'cache' would get instantiated once per
classloader...
