We've got following bug reported multiple times by users of SmartGit 6.5 which uses SWT 4.4.0: java.lang.IllegalArgumentException at org.eclipse.swt.SWT.error(SWT.java:4422) at org.eclipse.swt.SWT.error(SWT.java:4356) at org.eclipse.swt.SWT.error(SWT.java:4327) at org.eclipse.swt.graphics.TextLayout._getOffset(TextLayout.java:2095) at org.eclipse.swt.graphics.TextLayout.getPreviousOffset(TextLayout.java:2354) at org.eclipse.swt.custom.StyledText.getBoundsAtOffset(StyledText.java:3650) at org.eclipse.swt.custom.StyledText.setCaretLocation(StyledText.java:8509) at org.eclipse.swt.custom.StyledText.setCaretLocation(StyledText.java:8500) at org.eclipse.swt.custom.StyledText.updateSelection(StyledText.java:10342) at org.eclipse.swt.custom.StyledText.handleTextChanged(StyledText.java:6253) at org.eclipse.swt.custom.StyledText$6.textChanged(StyledText.java:5643) at org.eclipse.swt.custom.StyledTextListener.handleEvent(StyledTextListener.java:71) at org.eclipse.swt.custom.DefaultContent.sendTextEvent(DefaultContent.java:797) at org.eclipse.swt.custom.DefaultContent.replaceTextRange(DefaultContent.java:790) at org.eclipse.swt.custom.StyledText.handleCompositionChanged(StyledText.java:5827) at org.eclipse.swt.custom.StyledText$8.handleEvent(StyledText.java:5689) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4353) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1061) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1085) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1070) at org.eclipse.swt.widgets.IME.WM_IME_COMPOSITION(IME.java:387) at org.eclipse.swt.widgets.Canvas.WM_IME_COMPOSITION(Canvas.java:366) at org.eclipse.swt.widgets.Control.windowProc(Control.java:4636) at org.eclipse.swt.widgets.Canvas.windowProc(Canvas.java:339) at org.eclipse.swt.widgets.Display.windowProc(Display.java:5023) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:2549) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3759) Unfortunately, I have no snippet or steps to reproduce.

This error is one of the most reported bugs for SmartGit (78 crash logs, 20 more detailled reports). Hence, I'm increasing the importance.

Hard to fix without any reproducible scenario but one possible harmless fix that might help is to change line 3666 in StyledText.java from int offsetInLine = offset - lineOffset; to int offsetInLine = Math.max (0, offset - lineOffset); Thomas, do you think it is possible to test this change in SmartGit's SWT bundle and confirm before we actually integrate it in a release?
Unfortunately, no user has provided reproducible steps. I want to avoid building SWT myself.
Current SWT error stack-trace doesn't print the 'offset' value, we don't know if it's going negative or greater than text array length. Detailed the SWT error with 'offset' value in TextLayout._getOffset(), vai below git commit: http://git.eclipse.org/c/platform/eclipse.platform.swt.git/commit/?id=aa5e1f529d6cb38f7ba5b2ed1cb51812ef434823 Thomas: Please share/attach stack-trace(s) with offset information.

Going by the code it highly possible that below method call which is common across all stack-trace, is getting called with negative 'offset' value only and same gets passed to TextLayout._getOffset() and is leading to this problem: org.eclipse.swt.graphics.TextLayout.getPreviousOffset(int offset, int movement) Working on a fix by adding a lower-cap of 0 to 'offset' value(as suggested in comment 4 by Arun) at below method calls in StyledText class: - StyledText.getBoundsAtOffset() - StyledText.getPointAtOffset()

(In reply to Thomas Singer from comment #5) > Unfortunately, no user has provided reproducible steps. I want to avoid > building SWT myself. Hi Thomas, Going by various stack-traces available, we have made required changes. Can you try 4.6 M2 build & see if it fixes the problem in your product ?
I've built our new SWT jars from the latest code and released them with the latest preview build. It will take some time to verify that the problem has been solved by not occurring exceptions.
We are still getting reports with SWT 4.610: java.lang.IllegalArgumentException at org.eclipse.swt.SWT.error(SWT.java:4484) at org.eclipse.swt.graphics.TextLayout._getOffset(TextLayout.java:2102) at org.eclipse.swt.graphics.TextLayout.getPreviousOffset(TextLayout.java:2361) at org.eclipse.swt.custom.StyledText.getBoundsAtOffset(StyledText.java:3670) at org.eclipse.swt.custom.StyledText.setCaretLocation(StyledText.java:8555) at org.eclipse.swt.custom.StyledText.setCaretLocation(StyledText.java:8546) at org.eclipse.swt.custom.StyledText.updateSelection(StyledText.java:10405) at org.eclipse.swt.custom.StyledText.handleTextChanged(StyledText.java:6263) at org.eclipse.swt.custom.StyledText$6.textChanged(StyledText.java:5663) at org.eclipse.swt.custom.StyledTextListener.handleEvent(StyledTextListener.java:71) at org.eclipse.swt.custom.DefaultContent.sendTextEvent(DefaultContent.java:797) at org.eclipse.swt.custom.DefaultContent.replaceTextRange(DefaultContent.java:790) at org.eclipse.swt.custom.StyledText.handleCompositionChanged(StyledText.java:5847) at org.eclipse.swt.custom.StyledText$8.handleEvent(StyledText.java:5709) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:85) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4373) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1113) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1137) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1122) at org.eclipse.swt.widgets.IME.WM_IME_COMPOSITION(IME.java:389) at org.eclipse.swt.widgets.Canvas.WM_IME_COMPOSITION(Canvas.java:373) at org.eclipse.swt.widgets.Control.windowProc(Control.java:4710) at org.eclipse.swt.widgets.Canvas.windowProc(Canvas.java:344) at org.eclipse.swt.widgets.Display.windowProc(Display.java:5061) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:2552) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3777) ...

Hi Thomas, Fix in comment 10 already has a check in StyledText.getBoundsAtOffset() which should have avoided above stack-trace for negative offsets. Can you please confirm if this stack-trace occurred with my fix and has over-shot value which is non-negative ? Also I have already updated the logging mechanism(commit in comment 6) to print the offset in the log which should look something like below(for offset value -1): java.lang.IllegalArgumentException: Index out of bounds [offset value: -1] at org.eclipse.swt.SWT.error(SWT.java:4514) at org.eclipse.swt.graphics.TextLayout._getOffset(TextLayout.java:2144) at org.eclipse.swt.graphics.TextLayout.getPreviousOffset(TextLayout.java:2410) at org.eclipse.swt.custom.StyledText.getBoundsAtOffset(StyledText.java:3700) > Unfortunately, no user has yet provided exact steps how to reproduce. Keep looking for so that we could fix the root cause and not the symptoms.

The full data only is available if the user accepts to send the full log.
Luckily a few users have reported full logs. The exception message looks like: java.lang.IllegalArgumentException: Index out of bounds [offset value: 8] at org.eclipse.swt.SWT.error(SWT.java:4484) at org.eclipse.swt.graphics.TextLayout._getOffset(TextLayout.java:2102) at org.eclipse.swt.graphics.TextLayout.getPreviousOffset(TextLayout.java:2361) or java.lang.IllegalArgumentException: Index out of bounds [offset value: 15] at org.eclipse.swt.SWT.error(SWT.java:4484) at org.eclipse.swt.graphics.TextLayout._getOffset(TextLayout.java:2102) at org.eclipse.swt.graphics.TextLayout.getPreviousOffset(TextLayout.java:2361)
Could it be related to bug 481814?
(In reply to Thomas Singer from comment #20) > Could it be related to bug 481814? No, this looks like a different issue.
