Hi, This is a fix for an old bug which rightfully remarks that whereas access to 'level' in handler is synchronized, access to other mutable fields - like 'filter' etc... is not - which is inconsistent.
<http://cr.openjdk.java.net/~dfuchs/webrev_6823527/webrev.00/> I have tried to keep the fix simple - simply adding synchronized to method declarations when it was clear that there was an inconsistency. I also looked at the subclasses of j.u.l.Handler In some places I resorted to using a synchronized block to avoid calling overridable / external method from within the lock. The changed methods are simple accessors, and subclasses of Handler are already full of synchronized methods (e.g. methods like publish(...) are already synchronized) so the risk of fixing these simple accessors should be limited. best regards, -- daniel
