1522954 - GeckoLoader obtaining a serial number is not compatible with isolatedProcess

Status: RESOLVED DUPLICATE of bug 1523639

(Core :: Security: Process Sandboxing, defect, P3)

Description

The error is a bit strange as previous operations on Context do work, thought it makes sense we can't get serial numbers in the sandbox. This code seems to be entirely optional given that it's conditional on the SDK.

Adding null checks doesn't work, so I wonder if Android and its JIT are getting confused as to what the source of the failure is. Skipping the call is OK.
