Build Identifier: M20110909-1335 I sometimes encounter a freezing Eclipse when I apply a refactoring or quickfix (e.g., rename, extract method, create local variable / field) after the refactoring is executed, but while displaying the corresponding linked mode. Here's the stack trace: org.eclipse.swt.SWTException: Widget is disposed >---at org.eclipse.swt.SWT.error(SWT.java:4282) 1356 >---at org.eclipse.swt.SWT.error(SWT.java:4197) 1357 >---at org.eclipse.swt.SWT.error(SWT.java:4168) 1358 >---at org.eclipse.swt.widgets.Widget.error(Widget.java:466) 1359 >---at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:403) 1360 >---at org.eclipse.swt.widgets.Control.getParent(Control.java:2632) 1361 >---at org.eclipse.swt.widgets.Shell.getShells(Shell.java:1133) 1362 >---at org.eclipse.swt.widgets.Shell.updateMinimized(Shell.java:2269) 1363 >---at org.eclipse.swt.widgets.Shell.gtk_window_state_event(Shell.java:1428) 1364 >---at org.eclipse.swt.widgets.Widget.windowProc(Widget.java:1759) 1365 >---at org.eclipse.swt.widgets.Control.windowProc(Control.java:5016) 1366 >---at org.eclipse.swt.widgets.Display.windowProc(Display.java:4408) 1367 >---at org.eclipse.swt.internal.gtk.OS._gtk_main_do_event(Native Method) 1368 >---at org.eclipse.swt.internal.gtk.OS.gtk_main_do_event(OS.java:8422) 1369 >---at org.eclipse.swt.widgets.Display.eventProc(Display.java:1245) 1370 >---at org.eclipse.swt.internal.gtk.OS._g_main_context_iteration(Native Method) 1371 >---at org.eclipse.swt.internal.gtk.OS.g_main_context_iteration(OS.java:2276) 1372 >---at org.eclipse.swt.widgets.Shell.setVisible(Shell.java:2051) 1373 >---at org.eclipse.jface.internal.text.link.contentassist.CompletionProposalPopup2.displayProposals(CompletionProposalPopup2.java:683) 1374 >---at org.eclipse.jface.internal.text.link.contentassist.CompletionProposalPopup2.showProposals(CompletionProposalPopup2.java:227) 1375 >---at org.eclipse.jface.internal.text.link.contentassist.ContentAssistant2.showPossibleCompletions(ContentAssistant2.java:1265) 1376 >---at org.eclipse.jface.text.link.LinkedModeUI.triggerContentAssist(LinkedModeUI.java:824) 1377 >---at org.eclipse.jface.text.link.LinkedModeUI.switchPosition(LinkedModeUI.java:860) 1378 >---at org.eclipse.jface.text.link.LinkedModeUI.next(LinkedModeUI.java:799) 1379 >---at org.eclipse.jface.text.link.LinkedModeUIProposalListener.proposalChosen(LinkedModeUI.java:559) 1380 >---at org.eclipse.jface.internal.text.link.contentassist.ContentAssistant2.fireProposalChosen(ContentAssistant2.java:1544) 1381 >---at org.eclipse.jface.internal.text.link.contentassist.CompletionProposalPopup2.insertProposal(CompletionProposalPopup2.java:434) 1382 >---at org.eclipse.jface.internal.text.link.contentassist.CompletionProposalPopup2.selectProposalWithMask(CompletionProposalPopup2.java:363) 1383 >---at org.eclipse.jface.internal.text.link.contentassist.CompletionProposalPopup2.verifyKey(CompletionProposalPopup2.java:771) 1384 >---at org.eclipse.jface.internal.text.link.contentassist.ContentAssistant2InternalListener.verifyKey(ContentAssistant2.java:631) 1385 >---at org.eclipse.jface.text.TextViewerVerifyKeyListenersManager.verifyKey(TextViewer.java:491) 1386 >---at org.eclipse.swt.custom.StyledTextListener.handleEvent(StyledTextListener.java:65) 1387 >---at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) 1388 >---at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1258) 1389 >---at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1282) 1390 >---at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1267) 1391 >---at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:1061) 1392 >---at org.eclipse.swt.custom.StyledText.handleKeyDown(StyledText.java:5936) 1393 >---at org.eclipse.swt.custom.StyledText7.handleEvent(StyledText.java:5635) 1394 >---at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) 1395 >---at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1258) 1396 >---at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1282) 1397 >---at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1267) 1398 >---at org.eclipse.swt.widgets.Widget.sendKeyEvent(Widget.java:1294) 1399 >---at org.eclipse.swt.widgets.Widget.gtk_key_press_event(Widget.java:730) 1400 >---at org.eclipse.swt.widgets.Control.gtk_key_press_event(Control.java:3019) 1401 >---at org.eclipse.swt.widgets.Composite.gtk_key_press_event(Composite.java:734) 1402 >---at org.eclipse.swt.widgets.Widget.windowProc(Widget.java:1743) 1403 >---at org.eclipse.swt.widgets.Control.windowProc(Control.java:5016) 1404 >---at org.eclipse.swt.widgets.Display.windowProc(Display.java:4408) 1405 >---at org.eclipse.swt.internal.gtk.OS._gtk_main_do_event(Native Method) 1406 >---at org.eclipse.swt.internal.gtk.OS.gtk_main_do_event(OS.java:8422) 1407 >---at org.eclipse.swt.widgets.Display.eventProc(Display.java:1245) 1408 >---at org.eclipse.swt.internal.gtk.OS._g_main_context_iteration(Native Method) 1409 >---at org.eclipse.swt.internal.gtk.OS.g_main_context_iteration(OS.java:2276) 1410 >---at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3207) Reproducible: Sometimes Steps to Reproduce: 1.Missing object field member 2.Apply quick fix "create field" 3.Eclipse freezes
Did you get an exception (the stack trace look like this)? Could you take a VM dump while it is freezing?
(In reply to comment #1) > Did you get an exception (the stack trace look like this)? Could you take a VM > dump while it is freezing? I attached the stack traces. Please do not hesitate to ask me if you have further questions concerning this ticket. Thanks, Michael

This is a duplicate of bug 354842. I expect that you see similar freezes with other hovers and tooltips as well. Please also try the workaround mentioned in bug 354842 comment 2. *** This bug has been marked as a duplicate of bug 354842 ***
I tried the workaround mentioned in bug 354842 comment 2 (disabling animations). But this did not make any difference for me! The problem still occurs.
