Repro Project

*** Overview ***
If an app contains a WebView and a new thread is created, the app will crash when ran on a device on Android 5.1.

I tested the repro project on a Nexus 5 running 5.1 to reproduce the crash. A customer also reports that the issue occurs on a Nexus 7(2012) on 5.1. 

However, testing on a Nexus 7(2013) running 5.0 did not reproduce the crash so the issue might only be in Android 5.1. 


*** Steps to Reproduce ***
1. Run the repro project on a Android device running 5.1
2. Click the “TEST” button


*** Actual Results ***
The new thread will run and complete, but then the app will throw an unhandled exception and crash. I’ve attached the debug output to the report.


*** Expected Results ***
The new thread completes successfully and does not cause the app to crash.


*** Environment Info ***

Can you still reproduce with latest version of XA? I cannot reproduce with XA 8.3.0.5 on a Pixel, so maybe the device is at fault. Thank you.
