During a "New" wizard, if an SWTError is thrown while building a wizard page, the error is not handled, and the IDE process terminates abnormally (i.e. no proper shutdown allowing edit sessions to save). This will cause data loss and perceived instability in the IDE. The problem is likely going to happen with any runtime exception, but I've only seen it with SWTError. In particular, an SWTError was thrown under Linux when Combo.setItems(list) was called where list[0] == null. This doesn't cause an SWTError in Windows. To reproduce this, take any New wizard (eg new Java Project). In the createControl() method that builds the wizard page content as called by Wizard.createPageControls, manually throw an SWTError (throw new SWTError("oops");). This is just to simulate an actual SWTError that might be thrown for a variety of legitimate reasons such as low system resources. With that throw in place, run the IDE and attempt to create the new object. When you click Next from the first wizard page, and it attempts to build the page we modified createControl for, the IDE will simply shut down. I expected that the error would be caught, and the current operation (creating a new Java Project for example) would fail and info written to .log. Here is the stack trace that was dumped to stdout in my case: org.eclipse.swt.SWTError: Item not added at org.eclipse.swt.SWT.error(SWT.java:1724) at org.eclipse.swt.SWT.error(SWT.java:1741) at org.eclipse.swt.widgets.Widget.error(Widget.java:262) at org.eclipse.swt.widgets.Combo.setItems(Combo.java:1142) at com.ibm.etools.j2ee.common.wizard.NewJ2EEProjectCreationPage.populateEARProjectCombo(NewJ2EEProjectCreationPage.java:148) at com.ibm.etools.j2ee.common.wizard.NewJ2EEProjectCreationPage.createControl(NewJ2EEProjectCreationPage.java:54) at org.eclipse.jface.wizard.Wizard.createPageControls(Wizard.java:158) at org.eclipse.jface.wizard.WizardDialog.createPageControls(WizardDialog.java:485) at org.eclipse.jface.wizard.WizardDialog.setWizard(WizardDialog.java:835) at org.eclipse.jface.wizard.WizardDialog.showPage(WizardDialog.java:870) at org.eclipse.jface.wizard.WizardDialog.nextPressed(WizardDialog.java:648) at org.eclipse.jface.wizard.WizardDialog.buttonPressed(WizardDialog.java:288) at org.eclipse.jface.dialogs.Dialog$1.widgetSelected(Dialog.java:236) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:69) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java(Compiled Code)) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:505) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java(Compiled Code)) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java(Compiled Code)) at org.eclipse.jface.window.Window.runEventLoop(Window.java(Compiled Code)) at org.eclipse.jface.window.Window.open(Window.java:517) at org.eclipse.ui.actions.NewWizardAction.run(NewWizardAction.java:63) at org.eclipse.ui.internal.NewWizardDropDownAction.run(NewWizardDropDownAction.java:68) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:398) at org.eclipse.jface.action.ActionContributionItem.handleWidgetEvent(ActionContributionItem.java:352) at org.eclipse.jface.action.ActionContributionItem.access$0(ActionContributionItem.java:343) at org.eclipse.jface.action.ActionContributionItem$ActionListener.handleEvent(ActionContributionItem.java:47) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java(Compiled Code)) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:505) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java(Compiled Code)) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java(Compiled Code)) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java(Compiled Code)) at org.eclipse.ui.internal.Workbench.run(Workbench.java:642) at org.eclipse.core.internal.boot.InternalBootLoader.run(InternalBootLoader.java:810) at org.eclipse.core.boot.BootLoader.run(BootLoader.java:280) at java.lang.reflect.Method.invoke(Native Method) at org.eclipse.core.launcher.Main.basicRun(Main.java:119) at org.eclipse.core.launcher.Main.run(Main.java:401) For additional info, contact Steve Francisco (cisco@ca.ibm.com) NOTES: KH (9/20/2001 9:27:41 AM) Customer will fix their code. The request is to be more robust when errors happen.
PRODUCT VERSION: Eclipse build 134 and 135 (likely long before that too)
This is another case where we can improve stability/servicability.
*** Bug 2041 has been marked as a duplicate of this bug. ***
See bug 2041 - Comments: McQ 2002-01-29 10:12. We are changing it trying to make it more robust and trying to inform the user about the problem but it may not be possible do open a dialog. Depending on the Error that happened we may not have more handles or memory.
Released.
