System: Windows XP Final JDK 1.4 Beta 3 Netbeans 3.3 Beta 2 Operation: Load Netbeans, once netbeans is loaded (with the project I was last working on), I went to a directory in the filesystem view about 3 levels down, and right-clicked it (so I could create a new class). Nothing happened for the longest time. In fact, MSN Messenger for some reason decided to die with an exception about 10 seconds later, and THEN netbeans reported a "Class cast exception" with this stack trace: Thu Nov 01 15:22:13 GMT-07:00 2001: java.lang.ClassCastException: null Nested annotation: java.io.IOException java.lang.InternalError at org.netbeans.core.lookup.TMLookup$I.getInstance(TMLookup.java:115) at org.openide.util.lookup.AbstractLookup.lookup (AbstractLookup.java:235) at org.openide.util.lookup.ProxyLookup.lookup(ProxyLookup.java:121) at org.openide.explorer.ExplorerActions.getClipboard (ExplorerActions.java:328) at org.openide.explorer.ExplorerActions.attach(ExplorerActions.java:85) at org.openide.explorer.ExplorerPanel.componentActivated (ExplorerPanel.java:118) at org.netbeans.core.NbMainExplorer$MainTab.componentActivated (NbMainExplorer.java:673) at org.openide.windows.WindowManager.activateComponent (WindowManager.java:157) at org.netbeans.core.windows.WindowManagerImpl.activateComponent (WindowManagerImpl.java:710) at org.netbeans.core.windows.frames.DefaultContainerImpl.doActivateComponent (DefaultContainerImpl.java:546) at org.netbeans.core.windows.frames.DefaultContainerImpl.reactivateSelectedCompone nt(DefaultContainerImpl.java:714) at org.netbeans.core.windows.frames.DefaultContainerImpl$2.run (DefaultContainerImpl.java:873) at org.netbeans.core.windows.frames.DefaultContainerImpl$4.run (DefaultContainerImpl.java:888) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:181) [catch] at java.awt.EventQueue.dispatchEvent(EventQueue.java:446) at java.awt.EventDispatchThread.pumpOneEventForHierarchy (EventDispatchThread.java:193) at java.awt.EventDispatchThread.pumpEventsForHierarchy (EventDispatchThread.java:147) at java.awt.EventDispatchThread.pumpEvents (EventDispatchThread.java:141) at java.awt.EventDispatchThread.pumpEvents (EventDispatchThread.java:133) at java.awt.EventDispatchThread.run(EventDispatchThread.java:101) Thu Nov 01 15:22:13 GMT-07:00 2001: java.lang.ClassCastException: java.io.IOException java.lang.ClassCastException: java.io.IOException at sun.awt.datatransfer.ClipboardTransferable.fetchOneFlavor (ClipboardTransferable.java:144) at sun.awt.datatransfer.ClipboardTransferable.<init> (ClipboardTransferable.java:83) at sun.awt.datatransfer.SunClipboard.getContents(SunClipboard.java:83) at org.netbeans.core.CoronaClipboard.refreshClipboard (CoronaClipboard.java:125) at org.netbeans.core.CoronaClipboard.<init>(CoronaClipboard.java:91) at org.netbeans.core.CoronaClipboard.<init>(CoronaClipboard.java:66) at org.netbeans.core.NbTopManager.getClipboard(NbTopManager.java:485) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:42) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:28) at java.lang.reflect.Method.invoke(Method.java:327) at org.netbeans.core.lookup.TMLookup$I.getInstance(TMLookup.java:112) at org.openide.util.lookup.AbstractLookup.lookup (AbstractLookup.java:235) at org.openide.util.lookup.ProxyLookup.lookup(ProxyLookup.java:121) at org.openide.explorer.ExplorerActions.getClipboard (ExplorerActions.java:328) at org.openide.explorer.ExplorerActions.attach(ExplorerActions.java:85) at org.openide.explorer.ExplorerPanel.componentActivated (ExplorerPanel.java:118) at org.netbeans.core.NbMainExplorer$MainTab.componentActivated (NbMainExplorer.java:673) at org.openide.windows.WindowManager.activateComponent (WindowManager.java:157) at org.netbeans.core.windows.WindowManagerImpl.activateComponent (WindowManagerImpl.java:710) at org.netbeans.core.windows.frames.DefaultContainerImpl.doActivateComponent (DefaultContainerImpl.java:546) at org.netbeans.core.windows.frames.DefaultContainerImpl.reactivateSelectedCompone nt(DefaultContainerImpl.java:714) at org.netbeans.core.windows.frames.DefaultContainerImpl$2.run (DefaultContainerImpl.java:873) at org.netbeans.core.windows.frames.DefaultContainerImpl$4.run (DefaultContainerImpl.java:888) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:181) [catch] at java.awt.EventQueue.dispatchEvent(EventQueue.java:446) at java.awt.EventDispatchThread.pumpOneEventForHierarchy (EventDispatchThread.java:193) at java.awt.EventDispatchThread.pumpEventsForHierarchy (EventDispatchThread.java:147) at java.awt.EventDispatchThread.pumpEvents (EventDispatchThread.java:141) at java.awt.EventDispatchThread.pumpEvents (EventDispatchThread.java:133) at java.awt.EventDispatchThread.run(EventDispatchThread.java:101) As instructed, I have also attached my log file.
