This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
Scenario: - Create Args project - Select project in 'Projects' tab and call context menu. Select 'Step into' menu item ==> Debugger started - Push 'Window|Debugging|Dissambly' menu item - Move cursor on some register ==> On other machines tooltip appears. On my machine I see NPE (always) instead of tooltip. java.lang.NullPointerException at org.netbeans.modules.cnd.debugger.gdb.disassembly.DisToolTipAnnotation.run(DisToolTipAnnotation.java:121) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:561) [catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:986)
And other scenario: - Create Args project - Select project in 'Projects' tab and call context menu. Select 'Step into' menu item ==> Debugger started - Push 'Window|Debugging|Registers' menu item ==> NPE java.lang.NullPointerException at java.lang.String.compareTo(String.java:1168) at org.netbeans.modules.cnd.debugger.gdb.ui.RegistersTopComponent$1.compare(RegistersTopComponent.java:212) at org.netbeans.modules.cnd.debugger.gdb.ui.RegistersTopComponent$1.compare(RegistersTopComponent.java:211) at java.util.Arrays.mergeSort(Arrays.java:1270) at java.util.Arrays.mergeSort(Arrays.java:1282) at java.util.Arrays.mergeSort(Arrays.java:1281) at java.util.Arrays.mergeSort(Arrays.java:1282) at java.util.Arrays.mergeSort(Arrays.java:1282) at java.util.Arrays.sort(Arrays.java:1210) at java.util.Collections.sort(Collections.java:159) at org.netbeans.modules.cnd.debugger.gdb.ui.RegistersTopComponent$RegisterTableModel.refresh(RegistersTopComponent.java:205) at org.netbeans.modules.cnd.debugger.gdb.ui.RegistersTopComponent$RegisterTableModel.access$200(RegistersTopComponent.java:155) at org.netbeans.modules.cnd.debugger.gdb.ui.RegistersTopComponent.<init>(RegistersTopComponent.java:53) at org.netbeans.modules.cnd.debugger.gdb.ui.RegistersTopComponent.getDefault(RegistersTopComponent.java:87) at org.netbeans.modules.cnd.debugger.gdb.ui.RegistersTopComponent.findInstance(RegistersTopComponent.java:100) at org.netbeans.modules.cnd.debugger.gdb.ui.RegistersAction.actionPerformed(RegistersAction.java:25) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1995) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2318) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:387) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:242) at javax.swing.AbstractButton.doClick(AbstractButton.java:357) at javax.swing.plaf.basic.BasicMenuItemUI.doClick(BasicMenuItemUI.java:1220) at javax.swing.plaf.basic.BasicMenuItemUI$Handler.mouseReleased(BasicMenuItemUI.java:1261) at java.awt.Component.processMouseEvent(Component.java:6041) at javax.swing.JComponent.processMouseEvent(JComponent.java:3265) at java.awt.Component.processEvent(Component.java:5806) at java.awt.Container.processEvent(Container.java:2058) at java.awt.Component.dispatchEventImpl(Component.java:4413) at java.awt.Container.dispatchEventImpl(Container.java:2116) at java.awt.Component.dispatchEvent(Component.java:4243) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4322) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:3986) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:3916) at java.awt.Container.dispatchEventImpl(Container.java:2102) at java.awt.Window.dispatchEventImpl(Window.java:2440) at java.awt.Component.dispatchEvent(Component.java:4243) [catch] at java.awt.EventQueue.dispatchEvent(EventQueue.java:599) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:104) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:273) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:183) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:173) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:168) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:160) at java.awt.EventDispatchThread.run(EventDispatchThread.java:121)
Can you please fully characterize the machine on which this defect occurs: OS version, Java version etc. Also can you characterize one or two machines on which defect does NOT occur.
Assembler fails on such machine: SLES 9, 64-bit, java 1.6.0 (1.6.0_04 I think), gdb 6.6 Works correctly on Ubuntu 7 (32 but) and Fedora Core (32 bit)
Could you please attach gdb log
first part fixed in: http://hg.netbeans.org/main/rev/e6a900c24eca
Created attachment 59927 [details] gdb-log
The problem is that gdb gives 50 register names and 58 register values. I will fix exception, but we still have to find out why gdb reports inconsistent information on this platform, and what are those 8 extra registers we have values but not names for.
Could the extra values be because 8 registers are 64-bit and the rest 32-bit?
The problem is: gdb is asked for register names too early (before the debugged program is loaded) and gives 32-bit registers. After 64-bit program is loaded it uses 64-bit registers.
Fixed in the changeset: http://hg.netbeans.org/main/rev/64221f636744
Fixed in trunk. Escalated to P1. Request permission to fix in RC2.
verified in RC1 build + jar with fixes from developer
