Updated expectations in http://trac.webkit.org/projects/webkit/changeset/139168
(In reply to comment #20 from 106068) > Or maybe the compositor update should just bail if layout is dirty (as long as it will happen after the next layout). Ok. I will replace the assert with a return. I cannot reproduce any of the crashes in local, so I'm trying to build a test to always reproduce the issue. It looks like the common pattern is the java applet that triggers the scheduled compositor update.
I don't think it's right to use expectations / skipping to fix new failures with a known cause. A better approach is to contact the author and/or roll out the offending patch.
