This is being reported poorly on treeherder, sometimes as "PROCESS-CRASH | Automation Error: Missing end of test marker (process crashed?)" but logcats show the NPE. http://ftp.mozilla.org/pub/mozilla.org/mobile/tinderbox-builds/fx-team-android-api-11/1430421556/fx-team_ubuntu64_vm_armv7_mobile_test-robocop-4-bm116-tests1-linux64-build12.txt.gz 14:03:53 INFO - 04-30 13:30:56.299 E/GeckoCrashHandler( 1514): >>> REPORTING UNCAUGHT EXCEPTION FROM THREAD 81 ("Thread-81") 14:03:53 INFO - 04-30 13:30:56.299 E/GeckoCrashHandler( 1514): java.lang.NullPointerException 14:03:53 INFO - 04-30 13:30:56.299 E/GeckoCrashHandler( 1514): at org.mozilla.gecko.gfx.GeckoLayerClient.setFirstPaintViewport(GeckoLayerClient.java:590) 14:03:53 INFO - 04-30 13:30:56.299 E/GeckoCrashHandler( 1514): at dalvik.system.NativeStart.run(Native Method) 14:03:53 INFO - 04-30 13:30:56.299 E/GeckoCrashHandler( 1514): Main thread (1) stack: 14:03:53 INFO - 04-30 13:30:56.299 E/GeckoCrashHandler( 1514): android.os.MessageQueue.nativePollOnce(Native Method) 14:03:53 INFO - 04-30 13:30:56.329 E/GeckoCrashHandler( 1514): android.os.MessageQueue.next(MessageQueue.java:132) 14:03:53 INFO - 04-30 13:30:56.329 E/GeckoCrashHandler( 1514): android.os.Looper.loop(Looper.java:124) 14:03:53 INFO - 04-30 13:30:56.329 E/GeckoCrashHandler( 1514): android.app.ActivityThread.main(ActivityThread.java:5103) 14:03:53 INFO - 04-30 13:30:56.339 E/GeckoCrashHandler( 1514): java.lang.reflect.Method.invokeNative(Native Method) 14:03:53 INFO - 04-30 13:30:56.339 E/GeckoCrashHandler( 1514): java.lang.reflect.Method.invoke(Method.java:525) 14:03:53 INFO - 04-30 13:30:56.339 E/GeckoCrashHandler( 1514): com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:737) 14:03:53 INFO - 04-30 13:30:56.349 E/GeckoCrashHandler( 1514): com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 14:03:53 INFO - 04-30 13:30:56.349 E/GeckoCrashHandler( 1514): dalvik.system.NativeStart.main(Native Method)

I would be more worried if it keeps happening.

Failures in bug 1160560 are quite frequent now. I still think this was regressed by bug 1158309. Can you have a look?
Flags: needinfo?(nchen)
We now load Gecko sufficiently early that when the compositor first paints, the Java side may not have a selected tab yet (i.e. the initial tab hasn't been created on the Java side). I think this situation causes the NPE. This patch makes us ignore a null selected tab in setFirstPaintViewport. I think this is safe because once we do have a selected tab, we'll reset the viewport metrics again and everything should be back to normal?
