Hi JDT team, while Code Recommenders shows up in the stack, these two problems [1, 2] seems rather a) be caused by the new index and b) have the same root cause. From the message, I would guess that there is a confusion of object equality/identity somewhere, as close()V and close()V seems the be the same method. Hope this helps.

This stack indicates index corruption. If it's reproducible, the index's write log could be enabled to obtain a traceback of the sequence of writes that resulted in the corruption.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
