Hi Julien,

put this problem up in a seperate thread on the mailing list and tell
how the Java Objects have to look like. We should find a better solution
for that.

You must explain this to me in detail, because I don't understand why.
Actually I think we should avoid this.

As said already, lets fix this in the Bluetooth library itself. I know
that SDP itself is a horrible mess of object oriented stuff, but I think
we will find a solution for it.
