Our customers are seeing this problem too. Looks like the CDT search is looking for dirty editors but it's not using the UI thread. Here's the relevant log: !ENTRY org.eclipse.core.jobs 4 2 2011-10-13 16:45:07.011 !MESSAGE An internal error occurred during: "Search references". !STACK 0 org.eclipse.swt.SWTException: Invalid thread access at org.eclipse.swt.SWT.error(SWT.java:4282) at org.eclipse.swt.SWT.error(SWT.java:4197) at org.eclipse.swt.SWT.error(SWT.java:4168) at org.eclipse.swt.widgets.Widget.error(Widget.java:466) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:404) at org.eclipse.swt.widgets.Text.getTextChars(Text.java:1064) at org.eclipse.swt.widgets.Text.getText(Text.java:1008) at com.smartbear.collaborator.ui.review.GeneralInfoWidget.titleDirty(GeneralInfoWidget.java:558) at com.smartbear.collaborator.ui.review.GeneralInfoWidget.isDirty(GeneralInfoWidget.java:521) at com.smartbear.collaborator.ui.editors.ReviewEditor.isDirty(ReviewEditor.java:188) at org.eclipse.ui.internal.EditorManager.collectDirtyEditors(EditorManager.java:294) at org.eclipse.ui.internal.EditorManager.getDirtyEditors(EditorManager.java:587) at org.eclipse.ui.internal.WorkbenchPage.getDirtyEditors(WorkbenchPage.java:2153) at org.eclipse.cdt.ui.CUIPlugin.getDirtyEditors(CUIPlugin.java:760) at org.eclipse.cdt.internal.ui.search.PDOMSearchQuery.collectNames(PDOMSearchQuery.java:281) at org.eclipse.cdt.internal.ui.search.PDOMSearchQuery.createMatches(PDOMSearchQuery.java:372) at org.eclipse.cdt.internal.ui.search.PDOMSearchQuery.createMatches(PDOMSearchQuery.java:328) at org.eclipse.cdt.internal.ui.search.PDOMSearchTextSelectionQuery$1.runOnAST(PDOMSearchTextSelectionQuery.java:78) at org.eclipse.cdt.internal.core.model.ASTCache.runOnAST(ASTCache.java:223) at org.eclipse.cdt.internal.ui.editor.ASTProvider.runOnAST(ASTProvider.java:347) at org.eclipse.cdt.internal.ui.search.PDOMSearchTextSelectionQuery.runWithIndex(PDOMSearchTextSelectionQuery.java:55) at org.eclipse.cdt.internal.ui.search.PDOMSearchQuery.run(PDOMSearchQuery.java:498) at org.eclipse.search2.internal.ui.InternalSearchUI$InternalSearchJob.run(InternalSearchUI.java:91) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

This is a pretty severe issue. It happens whenever an editor is open which needs to access an SWT control to check its dirty state. This is true for many FormEditors, like the Plugin Manifest Editor. This is why I just ran into this.

Still happens in CDT 8.4.0.201406111759 1. Open a PDE editor with forms (plugin.xml) 2. Open a C/C++ source file with some variables 3.

The text search does a similar check on dirty editors, however it ignores all non text editors. We can do the same for CDT.
Fixed in master.
