    Description

      Some JNI methods have a isCopy pointer that should be set to JNI_FALSE/JNI_TRUE if a copy is not made/made.

      If we only consider cases where the methods return non NULL elements and then look at the isCopy value, there is one corner case where isCopy is not set.

      Which means a user could mistakenly do this:
          jboolean isCopy;
          boolOrig = env->GetBooleanArrayElements(arrayOrig, &isCopy);

      and if arrayOrig is of length 0, then isCopy is not set to JNI_FALSE.
