Apparently I was wrong; DataBuffer does indeed wrap a true Java array. E.g. With
the JDK, if a DataBuffer is constructed from a java array, changes in that array
will be reflected in the DataBuffer. Same goes for the array returned by
Databuffer.getData().
So this appears to be a bit of a conundrum. Perhaps DataBuffer could represent a
*pinned* java array, with the databuffer constructor pinning the array from the
native side and the destructor unpinning it? Is that legal? This won't help if
the array pointer returned by JNI is a copy though. Problematic.
