Can you provide stack traces? I'm surprised to see this as the
UpdateManager is supposed to be thread safe.
As a non-expert I just took a quick look at the latest Batik CVS
source. The UpdateManager's repaint() method looks like it needs a
synchronized block around its iterator. Also UpdateTracker.java (used
by UpdateManager) seems to use lots of unsynchronized collections.
Well the UpdateTracker is _not_ intended to be thread safe.
I'm not sure if the UpdateManager.repaint needs to be (in
other words does it have to support being called from
multiple threads concurrently) but I agree that locking on
the runnableQueue list is important - and that should have the
side effect of making it thread safe. Thanks!
