Yes, this looks better. At least by using reset() on the 
ByteArrayOutputStream we are eliminating one level of allocation and 
potential copying. Aaron managed to convince me that the 
ByteArrayOutputStream was better than using ByteBuffer, at least for 
now. However, there is still a bit too much copying going on - couldn't 
JdwpPacket.toBytes() write directly to the stream, instead of creating 
another temporary byte[]? That can be fixed in another patch, though.

I think I liked the old sendPacket() name better, but maybe thats just me :)

Otherwise, this looks OK.
