NPE

since updating from SVN this morning (2006/11/06) I'm getting the following exception:

Exception in thread "Thread-11" java.lang.NullPointerException
        at java.util.regex.Matcher.getTextLength(Matcher.java:1127)
        at java.util.regex.Matcher.reset(Matcher.java:284)

This exception only occurs on FreeBSD and Linux (CentOS), but works fine on Windows.

That's extremely bizarre!  I did nothing to anything that would have affected that!  I've been doing most my testing on Mac OS X, but also a little on Linux.  What did you update from?  (like had you been keeping up with SVN daily?)

[Dawie Malan]

Yes, I update daily, but I don't think it's something that you changed recently, I just haven't tried it on Linux until today.

I've done some more debugging, and it seems related to SSL. Have a look at this discussion: http://forum.java.sun.com/thread.jspa?threadID=567433&start=0.

I modified IncomingUSR.java a bit:

                        conn.setUseCaches(false);
                        Matcher matcher = passportUrlPattern.matcher(conn
                                .getHeaderField("PassportURLs"));

to

                        conn.setUseCaches(false);
                        conn.connect();
                        Matcher matcher = passportUrlPattern.matcher(conn
                                .getHeaderField("PassportURLs"));

Now I get this exception:

javax.net.ssl.SSLKeyException: RSA premaster secret error
        at com.sun.net.ssl.internal.ssl.PreMasterSecret.<init>(PreMasterSecret.java:86)
....
Caused by: java.security.NoSuchAlgorithmException: Cannot find any provider supporting RSA/ECB/PKCS1Padding
        at javax.crypto.Cipher.getInstance(DashoA12275)
....

I've installed the JCE Unlimited Strenght policy files, but it did not help.

What VM are you using?

I'm on Sun's JDK 1.5.0_06, but will try JRockit later tonight, maybe that solves the problem.

[Dawie Malan]

Apologies, it was caused by a classloading issue, and is work fine now.

[Daniel Henninger]

Whew.  =)  Thanks for letting me know!
