Description John Arthorne CLA 2011-12-19 15:41:29 EST 
Juno M4

I have hit a case using the mediawiki-to-eclipse-help ant task that hits an infinite loop. I left it for ten minutes and it never completed. CPU usage was constant for that process the entire time. Stacks coming...

Here is one wiki document that seems to cause it:

I reverted to the Indigo SR1 version of Mylyn WikiText and the problem went away, so this looks like a recent regression in Juno.

Thanks for the bug and stack traces.

I'm unable to reproduce this problem with my simple test case.  Can you please attach the Ant script that you're using to drive the conversion?

Comment 9 David Green CLA 2012-01-11 17:48:35 EST 
Thanks John.  I've run your Ant script locally and it completed just fine with the latest Mylyn WikiText (I'm using the "latest standalone distro":http://www.eclipse.org/downloads/download.php?file=/mylyn/snapshots/nightly/docs/wikitext-standalone-latest.zip ).  Can you try again (using the latest WikiText) and verify that it works for you?
Comment 10 John Arthorne CLA 2012-01-13 16:31:29 EST 
Yes, it appears to be working with the latest nightly snapshot! I guess this must be already fixed or a duplicate.. thanks for looking at it.
Comment 11 David Green CLA 2012-01-13 16:42:24 EST 
No problem, glad it's working now.
