Steps to reproduce:
1. Open Fennec
2. Go to https://adblockplus.org/devbuilds/adblockplus/adblockplus-2.0.4a.3399.xpi (http://goo.gl/jOSYR) and install the add-on
3. When install is complete, a popup is triggered. Tap on Restart button
4. After Fennec restarts, wait

Expected result:
No crash should occur

Actual result:
After step 4, Fennec will crash.

I guess that this crash might be related to this bug: https://crash-stats.mozilla.com/report/index/bp-1ada14c0-77cc-4924-a8f7-cd6832120503

Before performing step 2, I opened several webpages, each one in a new tab.

AndroidGLController::ProvideEGLSurface uses CallObjectMethod(mJObj, jProvideEGLSurfaceMethod) and then uses jObj without checking its return value (or checking for an exception -- return value might be bogus in this case anyway).  ProvideEGLSurface is throwing an exception here, as per the log:

E/SurfaceTexture(  117): [SurfaceView] connect: already connected (cur=1, req=1)
E/libEGL  (30454): EGLNativeWindowType 0xff860 already connected to another API

protct against exceptions

Protect against an exception raised java-side here.  I don't know why we're getting the exception or anything like that, but this stops a crash without any ill effects that I can see.

not enough volume to block on this, but nominate it for uplift once it lands on m-c and we'll probably take it.

I have no idea where that whitespace came from.  Now with CheckForException.

> xti, can you try to reproduce with tomorrow (Saturday's) nightly?

I cannot reproduce this issue anymore on the latest Nightly build. However, when I perform the str from comment #0, the following bugs can be reproduced: Bug 737928 (if I install the add-on without opening any webpage) and Bug 738935 (if ~3-4 webpages are opened in new tabs before installing the add-on).

I will close the bug as verified fixed on:

[Approval Request Comment]
User impact if declined: potential uncaught exception leading to GL weirdness
Testing completed (on m-c, etc.): on m-c for a few days
Risk to taking this patch (and alternatives if risky): very little; adds an exception check.  might introduce NULL-related crashes, but the alternative is random-memory-related crashes

Comment 15

This was approved for 14 (when 14 was Aurora) but never landed there. This is almost certainly what fixed the AndroidGLController::ProvideEGLSurface crashes on 15 and 16. Since these crashes are the #2 and #5 top crashers on 14.0b7 (Bug 763175, which is .N+ blocker), we should consider uplifting this to Beta.

[Triage Comment]

This can land on beta for 14.0.1 but please land on mozilla-beta tip only, not the release branch

This hasn't yet landed - is anything blocking?
Problem solved ;-)
