Whiteboard: [orange]
Mochitest run before and after this crash were green, so this looks random.
The crash log doesn't give me anywhere near enough information to work
with.  So we need to start looking for patterns.

1) How often do these crashes happen?

2) In which tests do they happen?

   There are a lot of other tests besides test_HTMLDocument07.html
   that load Java applets.

3) On which branches do they happen?

   test_HTMLDocument07.html appears to be exactly the same on the
   1.9.1 branch as it is on the 1.9.2 branch.  This is probably also
   true of many of the other tests that load Java applets.
This bug might be easier to figure out if the Mochitest crash logs
contained symbol information (including for the system calls, like
those from the Foundation framework).

Ted, do you know if this is something we can do?
It's a bit of a pain because we're generating the stack trace using Breakpad, so we'd have to have the system symbols available in Breakpad format. I think it's doable, I've filed bug 528231 with a proposal.
Thanks!

Mass marking whiteboard:[orange] bugs WFM (to clean up TBPL bug suggestions) that:
* Haven't changed in > 6months
* Whose whiteboard contains none of the strings: {disabled,marked,random,fuzzy,todo,fails,failing,annotated,leave open,time-bomb}
* Passed a (quick) manual inspection of bug summary/whiteboard to ensure they weren't a false positive.

I've also gone through and searched for cases where the whiteboard wasn't labelled correctly after test disabling, by using attachment description & basic comment searches. However if the test for which this bug was about has in fact been disabled/annotated/..., please accept my apologies & reopen/mark the whiteboard appropriately so this doesn't get re-closed in the future (and please ping me via IRC or email so I can try to tweak the saved searches to avoid more edge cases).
