Java error after update

There is a discussion going on over at comp.lang.java.programmer right 
now about this.  There was a change to the security policy on server 
sockets in _51.  With a SecurityManager you need permission to open a 
server socket outside of the user port range.

Just to be up front here, this is not my area of expertise (if there are 
any really).  You can look at the user port range with;

$ cat /proc/sys/net/ipv4/ip_local_port_range

I imagine (this is the part that is out of my area) that you could just 
change those port settings to get your program working again.  I have no 
idea what that does to anything else.  The other option is to set the 
security permissions for server sockets.  While I know that can be done, 
I have no idea how to do it.
