I can reproduce (what I think is) the crash in Eclipse 4.3 + Subclipse 1.10.6 + JavaHL 1.8.10 + Subversion 1.8.10.
If you have a Subversion config that allows use of gnome-keyring (e.g. a default or blank configuration on a Unix-like system), you'll get an unfriendly prompt that wants to disable all password caching. If you cancel that prompt, but then start connecting to authenticated Subversion repositories (via e.g. Window -> Open Perspective -> ... -> SVN repository exploring), you'll be able to crash Eclipse by trying to do operations that require credentials, like info or checkout. It pops up a dialog before it dies saying "An internal error occurred"..."invalid thread access". Here's some more information that I could find about the bug: Subversion dev post: http://subversion.1072662.n5.nabble.com/Problem-still-exists-with-GNOME-keyring-and-JavaHL-td63012.html Subclipse mailing list posts: http://subclipse.tigris.org/ds/viewMessage.do?dsForumId=1047&dsMessageId=2907280 http://permalink.gmane.org/gmane.comp.version-control.subversion.subclipse.user/16640 Cheers, Ben
