When we have a Java exception in native code, the Java stack in the exception will not be very useful because the top frame is the native entry point. In this case, the native stack is more useful. However, currently we don't get a good native stack in this situation because we go through Java when handling the exception, and the native stack we get will have a lot of unknown frames inside libdvm or libart. This patch makes us stay in native code when handling an uncaught exception from native code, so that we get a good native stack.
