Change EmptyArray System.identityHashCode to Object.hashCode. 

Equivalent behavior, improves performance since
Object.hashCode has a fast path in the java side that does not
require JNI.

According to traceview sampling profiler:
Calendar had 6.8% time in System.identityHashCode during launch.
0.4% time in System.identityHashCode after the change.
