Created attachment 193698 [details]
file which will reproduce the bug

jsp to reproduce the bug. either open it in wtp, or copy and paste it into a new jsp editor.

Comment 3 Patric Rufflar

2011-04-20 10:00:23 EDT

additional note to my previous attachement:

The test case reproduces a bug which might be different from the initial bug report/comment.

I had been confused, sorry.
 Maybe we should open another bug report for the provided test case.

Comment 4 Patric Rufflar

2011-05-04 12:21:57 EDT

Created attachment 194736 [details]
file which will reproduce the bug

This time providing the correct test case.
Just open the file within WTP to see the exception in your error log.

Comment 8 Philipp Groeschler

2012-03-21 08:50:38 EDT

Reproducible on Eclipse SDK 3.7.2 (M20120208-0800) with JavaScript Development Tools 1.3.2 (20120210195245).

Occurs quite often, sometimes more than once while editing a single line, and therefore is very annoying.

Comment 9 Todd Chaffee

2012-06-15 07:06:29 EDT

This happens so often I almost cannot use eclipse to edit javascript.  Is there a work-around?  Or can the priority be upped?

Comment 10 sinedanat Mising name

2012-07-17 16:35:00 EDT

I agree with Todd Chaffee - I can't use Eclipse for edit javascript files. It is still reproduced in Eclipse 4.2.0 too. It's a great pity.

Whoa... 4 years passed since the bug was submitted!
Is there any kind of workaround?
Eclipse eats all my CPUs and throws this error on each file save attempt.

I cannot reproduce any of exceptions by using the examples attached. Also, the line information in stacktraces is pretty outdated.

So, closing this issue with one exception: Bug #467319 is created with a fresh stacktrace attached. It looks like other exceptions aren't reproducible anymore.

Please, feel free to open new issues with fresh stacktraces and steps to reproduce (if possible).
