Research direction

Start with the Android 10 native backtrace and inspect StackSampler.java at line 64, then follow the caller in AbstractSampler.java at line 33. Determine the conditions that trigger the ART abort during thread stack sampling, and validate that sampling no longer causes the reported native crash on affected Android 10 devices.
