Fix races in trace_helper.cc We had an unfortunate race when stopping tracing with the trace_helper test code. This could lead to calling JNI methods with null or deleted global references. We fix this by using a JVMTI Raw Monitor and copying the global into a local ref. This allows us to safely disable tracing at any time from any thread. Test: ./test.py --host -j50 Bug: 69657830 Change-Id: I2f5daadddbde0cbd2f8453affb3871774837c47e
