[cas-dev] CAS version 3.0.7 and BlackBoard Version 6

[Darren Kraker]

We're trying to upgrade our CAS server from 2.x to 3.0.7 and are having 
trouble with the java casclient version 2.1.1.  The client works fine in 
all other environments but when running the jar file in the Blackboard 
tomcat app server we're getting a javax.net.ssl.SSLException: Invalid 
padding which is caused by javax.crypto.BadPaddingException: Invalid TLS 
padding: 101

I've added lots of debug code to the cas client to discover it fails on 
the call to getInputStream() within this block of SecureURL.java.

URLConnection uc = u.openConnection();
uc.setRequestProperty("Connection", "close");
r = new BufferedReader(new InputStreamReader(uc.getInputStream()));

I'm running
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Server VM (build 1.5.0_06-b05, mixed mode)

on Linux 2.4.21-32.0.1.ELsmp #1 SMP Tue May 17 17:52:23 EDT 2005 i686 
i686 i386 GNU/Linux

The same code when run outside tomcat runs fine.  Any ideas?
