                // In our experience this only happens under IBM 1.4.x when 
                // spurious (unrelated) certificates show up in the server' 
                // chain.  Hopefully this will unearth the real problem: 
                InputStream in = ssl.getInputStream();
                  If you're looking at the 2 lines of code above because 
                  you're running into a problem, you probably have two 
                    #1.  Clean up the certificate chain that your server 
                         is presenting (e.g. edit "/etc/apache2/server.crt" 
                         or wherever it is your server's certificate chain 
                         is defined). 
                    #2.   Upgrade to an IBM 1.5.x or greater JVM, or switch 
                          to a non-IBM JVM. 
                // If ssl.getInputStream().available() didn't cause an 
                // exception, maybe at least now the session is available? 
                session = ssl.getSession();
                if (session == null) {
                    // If it's still null, probably a startHandshake() will 
                    // unearth the real problem. 
                    // Okay, if we still haven't managed to cause an exception, 
                    // might as well go for the NPE.  Or maybe we're okay now? 
                    session = ssl.getSession();
            Certificate[] certs;
            try { 
                certs = session.getPeerCertificates();
            } catch (SSLPeerUnverifiedException spue) {
                InputStream in = ssl.getInputStream();
                // Didn't trigger anything interesting?  Okay, just throw 
                // original. 
                throw spue;
