# Reason for removal
Recent reports in gitter about issues related to desugaring not working in case of subclasses of ByteBuffer. In particular `DirectByteBuffer`.
Issue caused in not proper VTable for subclass in particular, methods injected into ByteBuffer during desugaring were not available in subclass.
This caused wrong method to be invoked (like `DirectByteBuffer.load()` instead of `ByteBuffer.clear()`).
The reason of this is the way how VTable is build: soot classes are used as source for methods. But these don't include injected/synthetic method (especially if class was build in previous session).
Reworking `VTable` to use `classinfo` instead of soot class is possible but already looks as overcomplicated thing if comparing to override methods.
The fix:
RoboVM's runtime `ByteBuffer` class was extended with API from Java9, no need in desugaring in this case:
```
public ByteBuffer flip()
public ByteBuffer clear()
public ByteBuffer mark()
public ByteBuffer reset()
public ByteBuffer rewind()
public ByteBuffer position(int newPosition)
public ByteBuffer limit(int newLimit)
```
