Can you reproduce this? If so, can you please provide the steps to reproduce it?
Jay, can you please follow up? Thanks!
(In reply to comment #2) > Can you reproduce this? If so, can you please provide the steps to reproduce > it? it works fine before. just found this exception these days. maybe related some of the Cache data?
(In reply to comment #4) > maybe related some of the Cache data? Perhaps. If this happens again, please update us with the steps.
(In reply to comment #5) > (In reply to comment #4) > > maybe related some of the Cache data? > > Perhaps. If this happens again, please update us with the steps. 1. Navigate -> open type in Hierarchy 2. type the class name in my project -> ok 3. get error dialog: Creating hierarchy failed. See log for details. See error log for more details. then I go to error log and found that stack trace. however, it seems some classes are no problem. while some got this exception. it seems jdt cache/index broken?
(In reply to comment #6) > it seems jdt cache/index broken? Possible, although I can't confirm. Feel free to reopen it if you see this again.
