The methods in java.util.zip.{CRC,Inflater,Deflater,Alder32} that accept a ByteBuffer need to be update to deal with a ByteBuffer that is backed by a MemorySegment in a shared arena, e.g. the following throws UOE:
var crc = new CRC32();
try (var arena = Arena.ofShared()) {
ByteBuffer bb = arena.allocate(100).asByteBuffer();
crc.update(bb);
}
In implementation terms, the use of ((DirectBuffer)buffer).address() in these classes need to change to use NIO_ACCESS.getBufferAdress().
var crc = new CRC32();
try (var arena = Arena.ofShared()) {
ByteBuffer bb = arena.allocate(100).asByteBuffer();
crc.update(bb);
}
