N20060407-0010 Invoke quick fix on the error in the class below -> CCE, adding unimplemented methods does not work. import org.eclipse.jface.viewers.IOpenListener; public class Test { private final class TestOpenListener implements IOpenListener { } } Steps to reproduce: - import org.eclipse.jface as binary plugin - create a new Java Project with src folder - add project org.eclipse.jface to build path - create class above and press Ctrl+1 on the line with error java.lang.ClassCastException: org.eclipse.jdt.internal.core.JavaProject at

Works for me. I get: public void open(OpenEvent event) { // TODO Auto-generated method stub } added in the TestOpenListener class. I am also using N20060407-0010.
Darn! I didn't make up that exception... I also cannot reproduce any more. When it happened, I could easily reproduce. OK to close (unless you see in the code how this could occur, or you want to add a check for this case).
Jérôme, Do you see how this would be possible? I could not reproduce the failure. Would you recommend that a check is added?
sorry, no idea how this can happen
Closing as WORKSFORME. Please reopen if it happens again.
Reopening as I was able to reproduce with steps from bug 136016
