Example file, opening this caused the deadlock which jstack.txt refers to

Installed Mylyn/WikiText which works well for small test inputs, but freezes the IDE with ~100% CPU load when
- pasting a larger document copied from Wikipedia editor
 -or-
- opening a .mediawiki file (prepared earlier outside of Eclipse) by double-clicking it.

Starting with an empty .mediawiki file, then adding sections from TextEditorSupport.mediawiki piecemeal causes the freeze to happen at about the ==In-browser editors== section. Splitting the file in to at this point doesn't freeze.
VM memory setting issue? If so, an error message would be much better than a freeze.

Splitting the file in to -> Splitting the file in two files

Thanks for the bug report Alain.  Does the problem just occur with the content you've provided, or does it occur with other content as well?  When we've seen this before it has been related to specific syntax used rather than size of the content.

Thanks for the reassign, I wasn't sure about what category this should go in.

With manual testing with the attached file I've confirmed that this problem no longer occurs with the fix merged for bug 417481.  Please reopen this bug if the problem comes up again for you.
