Bug 273752 syncExec in org.eclipse.ui.internal.navigator.NavigatorContentService.getSourceOfContribution(Object) causes deadlock in test suite
The Platform UI test suite does not complete anymore - it hangs in the org.eclipse.ui.tests.dynamicplugins.EditorTests.testEditorClosure() test case. The hang is in the following code: final boolean[] flag = new boolean[] { false }; FrameworkListener listener = new FrameworkListener() { public void frameworkEvent(FrameworkEvent event) { if (event.getType() == FrameworkEvent.PACKAGES_REFRESHED) synchronized (flag) { flag[0] = true; flag.notifyAll(); } } }; context.addFrameworkListener(listener); packageAdmin.refreshPackages(bundles); synchronized (flag) { while (!flag[0]) { try { flag.wait(); } catch (InterruptedException e) { } } } The flag[0] is never set to true, which probably means that the PACKAGES_REFRESHED event is not fired.
