[and it doesn't work]

I can't solve your problem, but having done networking in MacPerl and 
Java, I have some thoughts:

1) Remember that Macs and PCs define lines differently.  Are you 
dealing with the \x0D vs \x0D\x0A issue?

2) I have found Java I/O much buggier than (Mac)Perl I/O, so would 
tend to look at the Java code first.  I specifically recall reading 
about bugs with line reading in some Java libraries.

3) A possibly useful experiment would be to test your Perl code 
against a Web server and your Java server with some other client. 
Ideally, you would want to use a Web server running on the PC, but 
any one would do; you will probably have to reset the port in your 
MacPerl code or on the server, of course.  To test the Java code, 
telnet might work.  It might be interesting to test from a telnet 
client on the PC and one on the Mac.  This might help identify 
newline issues.

Hope some of this rambling helps!
