Glassfish v2.x java.lang.SecurityException

[Pat Farrell]

I'm developing a plain servlet/JSP app, and running it on Glassfish with Netbeans. I use two computers to do the development, sync'd with SVN

For months, this has all worked perfectly.

Starting today, I switched to my big machine, compiled the code, and when I run it, it dies throwing the subject line exception.

I have no idea what changed, why it is throwing this.

A bit of the stack dump looks like:

java.lang.SecurityException: Access to default session denied
        at javax.mail.Session.getDefaultInstance(Session.java:321)
        at com.fnfbook.mail.MailReader.readAll(MailReader.java:161)
        at com.fnfbook.daemon.actors.MailReadingDaemon.doOnePass(MailReadingDaemon.java:58)

The code that is throwing it is:

        Properties props = new Properties();
        props.setProperty("mail.host", getHost());
        props.setProperty("mail.user", getUser());
        ImapAuth auth = new ImapAuth(getUser(), getPassword());
        PasswordAuthentication passAuth = auth.getPasswordAuthentication();
        Session theSession = Session.getDefaultInstance(props, auth);

It is the Session.getDefaultInstance that is complaining.

I have no idea even where to start chasing this down. Any help, pointers, etc. greatly appreciated.
