Description
We are calling Mozilla's NPN_ConvertPoint from a thread other than the main thread which is causing it to return invalid results and is causing some applets to not behave correctly.

I need this fixed, because JavaFX depends on this, so I reassign the issue to myself.

SQE_OK to defer this issue to 7u60
26-07-2013
Additional justification for deferral: This fix is risky since it deals with threading issues, it could easily add deadlocks or crashes which are far worse than this problem and we simply do not have time to deal with such issues.

Once I see SQE-OK - I'll mark this approved :-)

request for 7u40 deferral: not a showstopper, limited to Mozilla only.

Copy of related text from 8017311: ------------------------------------------------------ Not reproducible with Safari. Not reproducible with Firefox 20 & 7u25. Reproducible with Firefox 21 & 7u25. Reproducible with Firefox 21 & 7u40 Reproducible with Firefox 21 & 7u6 Reproducible with Firefox 24 & 7u40 Looks like the issue is reproducible in Firefox starting from version 21, in FF20 the applet woks as expected. ------------------------------------------------------

This function is called quite frequently and doesn't ever seem to be called from the main thread.
