Hi,
i stumbled over this as well some time ago. The Javadoc says this exception
happens when the ByteBuffer isn't backed by an accessible array, my finding
was it isn't guaranteed in any way it is - better do not rely on that
method.
Fortunately you can easily rewrite your code to
int len = in.remaining();
//(i do think your usage of limit() is not what you intend to do)
byte[] stream = new byte[len];
in.get(stream , 0, in.remaining());
hope that helps.
regards,
christian!
