src/share/classes/java/lang/invoke/AdapterMethodHandle.java:

   if (false && spreadArgCount > SPREAD_LIMIT)

```
       return false;
```

   if (false && slotCount + extractStackMove(target) > SPREAD_LIMIT)

       return null;  // perhaps spreading a long[] array is going to push too much

Why are these turned off?

src/share/classes/java/lang/invoke/MethodHandleImpl.java:

```
       assert(false);  //OBS
```

"OBS"? Obsolete?

Otherwise looks good.
