Build Identifier: 3.6.1 Almost every time i try to rename/move file inside workspace i got an internal error. Sometimes my eclipse hangs for a long time (>1m) before error appears. If i repeat rename/move after error it works ok. i dont know if this is specific error to my plugin/workspace configuration, because i had the same error on 3.4, but i re-created my workspace from scratch and error looks like related to Eclipse core Log contents: !ENTRY org.eclipse.ltk.ui.refactoring 4 10000 2010-12-23 14:20:37.644 !MESSAGE Internal Error !STACK 0

Possibly caused by a corrupt extension point trying to participate in the refactoring.
can i do something to find this corrupted extension?
The problem is somewhere around PluginManifestChange.createRenameChange(PluginManifestChange.java:64), see the root exception in comment 0. The API IPluginExtension#getPoint() promises to return an ID, but both implementations can return null in some cases.
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.
