// findClassByLoaderFallback retries class resolution via the proxy class
// loader when JNI's default FindClass missed. Native threads see the
// bootstrap class loader, which can't resolve AAR/APK classes; the proxy
// classloader (set via SetProxyClassLoader) is the activity's
// PathClassLoader, which knows about every dexed class in the APK
// closure.
//
// Returns 0 when no proxy classloader has been installed or when the
// classloader doesn't know the class either.
