Re[2]: SocketNode - Unexpected Exception

[Yannick Menager <ym...@yahoo.co.uk>]

Hello Paul,

yup.. that's it exactly... that's the reason (or one of the reasons i
guess maybe) finalize is deprecated.... so don't use it... if you're
using 1.3, add a shutdown hook to do that cleanup (can't remember if
that was available under 1.2)

Best regards,
