Re: AW: [wtp-dev] WTP crashes often

[David M Williams <david_williams@xxxxxxxxxx>]

Thank you. 

When I said "sounds like a good
bug report", I meant a good issue to enter on our bug reporting system,
which can be found at 
https://bugs.eclipse.org/bugs/ 
You'll need an "id" if you
don't have one yet, but pretty painless. 
When you create a new report, you'd
select the "web tools" project and then 
the webools project again (I know, it
makes no sense :) 

That bugzilla system is the only way
we can systematically keep track of all the issues people tell us about.


But, curious, any chance this happends
if you change a file, then close the editor without saving it, 
and then next time you edit it or related
file, you see the problem? 

If so, sounds like it could be bug 210043
https://bugs.eclipse.org/210043

If this is the bug you are hitting,
the only work around is to close the workbench, and re-open it, after you
have to 
edit a file, then close it without saving
it. (And, of course, it's only certain files ... but, it's hard to describe

exactly which ones). 

This mailing list is mostly for committers
and contributors to WTP. Besides the bugzilla system, 
you might be interested in our webtools
newsgroup. 
http://www.eclipse.org/newsgroups/
That's the best places to ask questions
of a large auidence of fellow users. 

Thanks

Subject	AW: [wtp-dev] WTP crashes often

Hi again

I am so sorry, but I forgot to write, what I do, when the error occurs.
I edit either a jsp-page or the ejb-jar.xml file of my ejb-module.

Greetings,
Andreas Grund

Sounds like a good bug report. 

I've not seen this problem, (but, haven't searched bugzilla for it). 

Be sure to give lots of details like what you are editing, what else you
have installed, attach full logs and configuration data (from the about
box). 

Thanks,

Hi,

I work with the build M20070921-1145 on a Windows XP PC and my eclipse
WTP 

crashes regularly. I found the following error in the log file:

What is going wrong here and what do I have to do to stablize the eclipse
WTP?

Thanks for your help and best regards,
