Multipart mp = (Multipart) p.getContent() throws java.lang.ClassCastExcept

Question

I'm getting the following exception:
23:53:05,542 ERROR [BouncedMailJob] Exception javax.mail.internet.MimeMultipart
java.lang.ClassCastException: javax.mail.internet.MimeMultipart
        at com.imc.quartz.jobs.BouncedMailJob.dumpPart(BouncedMailJob.java:604)
        at com.imc.quartz.jobs.BouncedMailJob.execute(BouncedMailJob.java:287)
        at org.quartz.core.JobRunShell.run(JobRunShell.java:195)
        at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:520)in the code chunk:
      else if (p.isMimeType("multipart/*"))
         logger.debug("This is a Multipart");
         logger.debug("---------------------------");
         Multipart mp = (Multipart) p.getContent();    // This is the line throwing the exception
         level++;It's almost an exact carbon copy of msgshow.java in the demo, we just do some extra stuff with the results.
This code had been in production for a while, and I wanted to make a few minor updates, but now it's throwing the exception above on the line indicated. I've been looking at this all day and just cannot see what I might have introduced. Message is being passed in to dumpPart(), and the debug output does show I have a message.
What would cause this innocent looking line to throw that exception?
Any ideas?
Running on OSX 10.4.2, JBoss 4.0.3, using JAF 1.0.2 and JavaMail 1.3.3_01
Thanks.

try this
//get the content of the incoming mail and store as temp object
Object tmpobj = mimemsg.getContent();
if (tmpobj instanceof MimeMultipart) {
//Extract the multipart mail to a variable mp
MimeMultipart mp = (MimeMultipart) mimemsg.getContent();
}
