Did it occur that maybe the previous de-reference without a null check is the real problem ?
The proposed Raster change actually needs to be addressed as discussed inhttps://bugs.openjdk.java.net/browse/JDK-8255800 and so should not be part of this proposed change. DataBufferUShort may be the same.

But *all* of them need to be re-examined rather than just blindly updating them as some tool suggests.
