Bug 54094 Assertion failed in auto indent strategy
(in HEAD) The snippet editor subclasses the JavaSourceViewerConfiguration, and inherits its autoindent strategy. This is causing the following exception, when I attempt to enter a carriage return at the end of a snippet editor. For example, my editor cantained the following text. Placing the cursor at the end and pressing 'Enter' results in the stack trace. Should we not use the indent strategy? or can JUI allow us to continue using it? java.util.Vector v = null; v.add("Sam"); for (int i = 0; i < 100; i++) { } v.toString() org.eclipse.jface.text.Assert$AssertionFailedException: Assertion failed: at org.eclipse.jface.text.Assert.isTrue(Assert.java:175) at org.eclipse.jface.text.Assert.isTrue(Assert.java:160) at org.eclipse.jdt.internal.ui.text.JavaHeuristicScanner.scanForward (JavaHeuristicScanner.java:638) at org.eclipse.jdt.internal.ui.text.JavaHeuristicScanner.findNonWhitespaceForwardI nAnyPartition(JavaHeuristicScanner.java:607) at org.eclipse.jdt.internal.ui.text.JavaIndenter.skipToPreviousListItemOrListStart (JavaIndenter.java:759) at org.eclipse.jdt.internal.ui.text.JavaIndenter.findReferencePosition (JavaIndenter.java:559) at org.eclipse.jdt.internal.ui.text.JavaIndenter.findReferencePosition (JavaIndenter.java:405) at org.eclipse.jdt.internal.ui.text.JavaIndenter.getReferenceIndentation (JavaIndenter.java:105) at org.eclipse.jdt.internal.ui.text.JavaIndenter.computeIndentation (JavaIndenter.java:138) at org.eclipse.jdt.internal.ui.text.JavaIndenter.computeIndentation (JavaIndenter.java:124) at org.eclipse.jdt.internal.ui.text.java.JavaAutoIndentStrategy.smartIndentAfterNe wLine(JavaAutoIndentStrategy.java:261) at org.eclipse.jdt.internal.ui.text.java.JavaAutoIndentStrategy.customizeDocumentC ommand(JavaAutoIndentStrategy.java:996) at org.eclipse.jface.text.TextViewer.customizeDocumentCommand (TextViewer.java:3132) at org.eclipse.jface.text.TextViewer.handleVerifyEvent (TextViewer.java:3160) at org.eclipse.jface.text.TextViewer$TextVerifyListener.verifyText (TextViewer.java:322) at org.eclipse.swt.widgets.TypedListener.handleEvent (TypedListener.java:193) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:82) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:833) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:857) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:842) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:650) at org.eclipse.swt.custom.StyledText.modifyContent (StyledText.java:5951) at org.eclipse.swt.custom.StyledText.sendKeyEvent(StyledText.java:6935) at org.eclipse.swt.custom.StyledText.doContent(StyledText.java:2557) at org.eclipse.swt.custom.StyledText.handleKey(StyledText.java:5304) at org.eclipse.swt.custom.StyledText.handleKeyDown (StyledText.java:5327) at org.eclipse.swt.custom.StyledText$7.handleEvent (StyledText.java:5070) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:82) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:833) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:857) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:842) at org.eclipse.swt.widgets.Control.sendKeyEvent(Control.java:1716) at org.eclipse.swt.widgets.Control.sendKeyEvent(Control.java:1712) at org.eclipse.swt.widgets.Control.WM_CHAR(Control.java:3037) at org.eclipse.swt.widgets.Control.windowProc(Control.java:2940) at org.eclipse.swt.widgets.Display.windowProc(Display.java:2880) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:1376) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2031) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1509) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1480) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench (Workbench.java:257) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:139) at org.eclipse.ui.internal.ide.IDEApplication.run (IDEApplication.java:48) at org.eclipse.core.internal.runtime.PlatformActivator$1.run (PlatformActivator.java:260) at org.eclipse.core.runtime.adaptor.EclipseStarter.run (EclipseStarter.java:173) at org.eclipse.core.runtime.adaptor.EclipseStarter.run (EclipseStarter.java:106) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.eclipse.core.launcher.Main.basicRun(Main.java:305) at org.eclipse.core.launcher.Main.run(Main.java:745) at org.eclipse.core.launcher.Main.main(Main.java:713)
