Yes, binary properties can only be read as a whole (InputStream
returned is read-only) and stored back as a whole (new input stream).
I think the way to go is to copy the existing binary value (note: pseudo-code)
node.getProperty("jcr:data").getBinary().getInputStream()
into either a local file or an in-memory input stream, do your work
there and then finally store the whole stream again
node.setProperty("jcr:data", valueFactory.createBinary(stream))

Alex
