java.net.DatagramPacket: update to JDK 1.4 API (with attachment)

[Michael Koch <konqueror at gmx dot de>]

Hello list,


Another diff from me. Please review and comment. The intendation is different 
from the one used in other parts of the original file. I will re-indent the 
original file when this diff is commited. Can I silently commit the 
re-indented file afterwards (I mean without sending a diff here first) ?


Michael
