Hi, I downloaded build 200201030331 today. Now, whenever I do something that seems to affect the state of the IDE, I get this NPE: Thu Jan 03 12:19:36 EST 2002: java.lang.NullPointerException: <no message> java.lang.NullPointerException at org.netbeans.modules.java.JavaExecSupport$PropertyProxy.attachToDefault(JavaExecSupport.java:103) at org.netbeans.modules.java.JavaExecSupport.addProperties(JavaExecSupport.java:80) at org.netbeans.modules.java.JavaNode.createSheet(JavaNode.java:339) at org.openide.nodes.AbstractNode.getSheet(AbstractNode.java:315) at org.openide.nodes.AbstractNode.getPropertySets(AbstractNode.java:327) at org.openide.nodes.FilterNode.getPropertySets(FilterNode.java:419) at org.openide.explorer.propertysheet.PropertySheet.refreshPropertySheet(PropertySheet.java:419) at org.openide.explorer.propertysheet.PropertySheet.access$1100(PropertySheet.java:52) at org.openide.explorer.propertysheet.PropertySheet$3.run(PropertySheet.java:593) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:154) at java.awt.EventQueue.dispatchEvent(EventQueue.java:337) [catch] at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:131) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:98) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:93) at java.awt.EventDispatchThread.run(EventDispatchThread.java:85) This happens when I select a class in the explorer, when I move the cursor around in the editor but it doesn't happen if I open aor close a node in the explorer. If I select a node in the Explorer, it happens. I'm using JRE 1.3.1 on Linux. Maybe this has something to do with it: Thu Jan 03 12:04:12 EST 2002: java.lang.ClassCastException: Top component MyXmlClient not be loaded, either owning module was disabled, has incompatible version or top components settings file format is broken.

added zohar to the CC list. He also encountered this bug
Laurent, do you use 3.3.1-dev or dev builds?
3.3.1-dev.
