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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20630
