Description Gavin Barraclough 2010-01-25 16:28:23 PST
In JNIUtility.h, callJNIMethodV<jobject> might return null (from CallObjectMethodV, via JNICaller<jobject>::callV) if an exception is thrown.

All clients of callJNIMethodV<jobject> that are calling methods on the returned object should null check first.
