        Description

        The -Xcheck:jni option is an option that performs extra checks JNI code. It's frequently given to customers to determine whether they have a bug in their JNI code, which may cause some other problem. Running the jdk tests with this option causes this test failure:
        stdout: FATAL ERROR in native method: ReleasePrimitiveArrayCritical: unrecognized elements

        The -Xcheck:jni code checks the guard wrapper around the memory return by ReleasePrimitiveArrayCritical, matches that allocated with GetPrimitiveArrayCritical. Since there's no tag in this wrapper it looks like the memory wasn't allocated with GetPrimitiveArrayCritical (?)
