The first change, to remove SocketSecurityException seems benign. 
SocketSecurityException is a subclass of ExportException, so 
CommunicationException will continue to be thrown.

The second change, to replace RMISecurityManager with SecurityManager, 
will provide equivalent behavior, RMISecurityManager extends 
SecurityManager but does not add any state or behavior, but the runtime 
type of the security will be changed.

I've taken a quick look through the JDK source and cannot find any 
places where the type of the security manager is checked to see if it is 
an instance of RMISecurityManager. I also quickly looked in GrepCode, 
and could not find any either. Given this, I think the change should be ok.
