sending email from mac(10.6.6) using java (1.6.0_17)

I am trying to send an email from my java program. It worked when I was using earlier versions of java(on my 10.5 mac), but since I got 10.6.6 I can't send email from my app. The error I am getting is

javax.mail.MessagingException: Could not convert socket to TLS;

Could this:

Caused by: java.security.UnrecoverableKeyException: Password must not be null

be your problem? If not I would check that you have the correct SSL libraries after the update.

Edit: Assuming you're using openSSL, then and "openssl version" should do the trick. Also check that your "JAVA_HOME"/"JRE_HOME" and other such java environment variables are correctly set, and maybe follow this guy's solution to a similar problem. I have the sneaking suspicion your problems are related.
