Eclipse 4.3 (Kepler) with installed Plug-In WindowBuilder (from http://download.eclipse.org/windowbuilder/WB/integration/4.3/). Causes freeze while saving at ~ 60%. Components used: JFrame, JLabel, JTextField, JButton, JTable(with Models), JTabbedPanel, JPanel.
If i only add 2 components and save it, then its no problem with saving, but if i adding more than 5 components then its freezing while saving. Aborting saving doesnt help. So i press CTRL+Print to open my ScreenshotCapturer, to catch a screenshot then the saving is worked. Without the ScreenshotCapturer (my own written App in C#) i can't save my project in eclipse, because its freezed.
So i looked up in the workspace/.metadata/.log and found the NullPointerException that caused while saving:
!MESSAGE Designer [1.6.0.r43x201305211944.201308211039]: java.lang.NullPointerException !STACK 0 java.lang.NullPointerException at org.eclipse.wb.core.eval.AstEvaluationEngine$1.runObject(AstEvaluationEngine.java:65) at org.eclipse.wb.internal.core.utils.execution.ExecutionUtils.runObjectLog(ExecutionUtils.java:304) at org.eclipse.wb.core.eval.AstEvaluationEngine.evaluate(AstEvaluationEngine.java:63) at org.eclipse.wb.internal.swing.model.component.JTableInfo.evaluateColumnModelInvocations(JTableInfo.java:76) at org.eclipse.wb.internal.swing.model.component.JTableInfo.access$0(JTableInfo.java:69) at org.eclipse.wb.internal.swing.model.component.JTableInfo$1.evaluateAfter(JTableInfo.java:62) at sun.reflect.GeneratedMethodAccessor66.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.wb.core.model.broadcast.BroadcastSupport$1.intercept(BroadcastSupport.java:208) at org.eclipse.wb.core.model.broadcast.EvaluationEventListener$$EnhancerByCGLIB$$83eb11fe.evaluateAfter() at org.eclipse.wb.internal.core.parser.JavaInfoParser.evaluateNode(JavaInfoParser.java:1311) at org.eclipse.wb.internal.core.parser.JavaInfoParser.access$1(JavaInfoParser.java:1300) at org.eclipse.wb.internal.core.parser.JavaInfoParser$ExecutionFlowParseVisitor$3.run(JavaInfoParser.java:602) at org.eclipse.wb.internal.core.utils.execution.ExecutionUtils.runRethrow(ExecutionUtils.java:119) at org.eclipse.wb.internal.core.parser.JavaInfoParser$ExecutionFlowParseVisitor.postVisit(JavaInfoParser.java:592) at sun.reflect.GeneratedMethodAccessor24.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) .....
I opened the Java VisualVM to look what threads is running while freezed: RMI TCP Accept-0 100% AWT-Windows 100% Attach Listener 100% Signal Dispatcher 100% Main 100%
And the Heap is playing like crazy, goes up then goes down for every seconds.
Im using Windows 7 Professional with JRE 7 and JDK 7 (Both 64bit, Eclipse 64bit too).
I hope someone have the same problem and knows the solution.
