Bug 96814 Invalid thread access in "Searching for all types" - Open Type dialog
N20050526-0010 In a new workspace, I added all plugins to Java Search. Then I hit Ctrl+Shift+T. After the indexes were built and I started typing, a job error message came up: !ENTRY org.eclipse.core.runtime 4 2 2005-05-26 17:30:20.949 !MESSAGE An internal error occurred during: "Searching for all types". !STACK 0 org.eclipse.swt.SWTException: Invalid thread access at org.eclipse.swt.SWT.error(SWT.java:2940) at org.eclipse.swt.SWT.error(SWT.java:2863) at org.eclipse.swt.SWT.error(SWT.java:2834) at org.eclipse.swt.widgets.Display.error(Display.java:784) at org.eclipse.swt.widgets.Display.checkDevice(Display.java:613) at org.eclipse.swt.widgets.Display.disposeExec(Display.java:729) at org.eclipse.jdt.internal.ui.viewsupport.ImageDescriptorRegistry.hookDisplay(ImageDescriptorRegistry.java:85) at org.eclipse.jdt.internal.ui.viewsupport.ImageDescriptorRegistry.<init>(ImageDescriptorRegistry.java:48) at org.eclipse.jdt.internal.ui.viewsupport.ImageDescriptorRegistry.<init>(ImageDescriptorRegistry.java:36) at org.eclipse.jdt.internal.ui.JavaPlugin.internalGetImageDescriptorRegistry(JavaPlugin.java:790) at org.eclipse.jdt.internal.ui.JavaPlugin.getImageDescriptorRegistry(JavaPlugin.java:342) at org.eclipse.jdt.internal.ui.dialogs.TypeInfoViewer$TypeInfoLabelProvider.getImage(TypeInfoViewer.java:333) at org.eclipse.jdt.internal.ui.dialogs.TypeInfoViewer$AbstractSearchJob.internalRun(TypeInfoViewer.java:552) at org.eclipse.jdt.internal.ui.dialogs.TypeInfoViewer$AbstractSearchJob.doRun(TypeInfoViewer.java:473) at org.eclipse.jdt.internal.ui.dialogs.TypeInfoViewer$AbstractJob.run(TypeInfoViewer.java:439) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:67)
