JDK 7u on OS 10.8.2 with the latest public xcode
received the following error

---------------
The code that causes this error is the same in JDK 7 and JDK 8 :
    const SEL sel = sel_registerName(selNameAsChars);
    (*env)->ReleaseStringUTFChars(env, selName, selNameAsChars);
    return ptr_to_jlong(sel);


The error message seems to imply that users previously took advantage of the
returned pointer actually being the address of the string name, but now you
should call the getName function instead. That helpful message is going to
be wrong here since I believe we really *do* want the pointer and the correct fix is

-    return ptr_to_jlong(sel);
+    return ptr_to_jlong((void*)sel);

Can no one else in the world have tried building JDK7  with this latest xcode ?
Or is there something else likely to be the issue in his OS X envt ?
