[rules-users] Possible bug

[Pavel Tavoda]

Hello,
we are using official 5.0 release and sometimes (very rarely) we get
following error:
java.util.ConcurrentModificationException
	at java.util.HashMap$HashIterator.nextEntry(HashMap.java:793)
	at java.util.HashMap$ValueIterator.next(HashMap.java:822)

We are using AspectJ advice for starting rule evaluation for every
service call. Hope we are doing everything right in code. Full source
code of advice can be found at:
