while(true) in getConnectedSSLSocket Method in SMTPTransport.java

[Jason Warner <ja...@gmail.com>]

Hey all,

I was looking at the getConnectedSSLSocket method in the
SMTPTransport.javaclass for javamail and I was confused.  There is a
section that consists of
a while loop whose condition is true.  Within this while loop is code to
create a socket connection with a server.  I am confused as to how this
works.  Shouldn't there be some condition such that if the socket has been
connected then you break out of the while loop?  I used this piece of code
in the pop3Connection class for establishing an SSL connection when using
pop3.  When I try to run it I get a bind exception.  I believe this is
caused by that while loop not being exited when the socket is created.  I
can add in those break statements but I was curious how it works for smtp.
There are no break statements in that piece of code so I was wondering if
there's another way it works.  Is there a different reason why creating the
socket would break out of the while loop that I'm not encountering?  Thanks.

Jason

What you're seeing is code that's probably never been tested :-)   I 
suspect this has only ever been used with the non-factory version, and 
there should be a "break" right before the catch inside the loop.
