Research direction

Start with the supplied Android 11 Xiaomi 10 reproduction using ObjectBox 2.9.0 and Android Studio 4.1.3, then inspect the native crash frames in libobjectbox-jni.so and the profiler context. Done means identifying and fixing the SIGSEGV triggered by Android profiling, with the reproduction no longer crashing.
