java.util.ConcurrentModificationException

[Frederik Santens]

Hi,   We have a svg application that  updates a svg canvas via its updatemanager. The changes are triggered by a poller that polls for database changes. This poller runs in a separte thread. Every 2 seconds, a maximum of 400 svg parts can get updated. However we receive the following exception:     java.util.ConcurrentModificationException             at java.util.HashMap$HashIterator.nextEntry(HashMap.java:782)             at java.util.HashMap$KeyIterator.next(HashMap.java:818)             at org.apache.batik.gvt.UpdateTracker.getDirtyAreas(UpdateTracker.java:99)             at org.apache.batik.bridge.UpdateManager.repaint(Unknown Source)             at org.apache.batik.bridge.UpdateManager$UpdateManagerRunHander.runnableInvoked(Unknown Source)             at org.apache.batik.util.RunnableQueue.runnableInvoked(RunnableQueue.java:473)             at org.apache.batik.util.RunnableQueue.run(RunnableQueue.java:217)             at java.lang.Thread.run(Thread.java:534)   Any Idea’s?   Thx, Frederik --- Outgoing mail is certified Virus Free.
