    Description

      GetPrimitiveArrayCritical() can only be used with primitive array types, but logic in JNI_GetPrimitiveArrayCritical() makes it looks like possible for object array.

      BasicType type;
        if (a->is_objArray()) {
          type = T_OBJECT;
        } else {
          type = TypeArrayKlass::cast(a->klass())->element_type();
        }

      and I can pass in object array to GetPrimitiveArrayCritical() without any complains. See attached test case for details.
