PRODUCTION ISSUE - Receivemail java procedure

Question

Hi guys
I have this java program below, this program receives mail from a user general mailbox and displays it as in a Java Front End System as a request. Users are able to attach any type of attachments and even embedded emails.
My java program works for all attachments types except if the attachment is an email, it does not move it over or even recognize it. I thought it was because I was checking for attachments only for multipart emails but I tried checking for attachment for singlepart emails but I didn't get any desired results. Please help me guys as this is a production issue and I am on the line.
Here is the code:
DROP JAVA SOURCE CQ.RECEIVEMAIL;
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED CQ.RECEIVEMAIL as import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
import java.io.*;

import sqlj.runtime.*;
import oracle.sql.BLOB;

If your application use a lot of native code in same
process with jvm, errors in native part can easily
cause jvm fatal crashes. Some of such errors
reproduced only in stress condition (e.g. on
production server). -Xcheck:jni can help you in most
basic cases.
You can also try running some bounds checkers to
dinamicly verify you native code for pointer safety.Thanks for the quick response, zhmur.
Do you have any pointers to documentation regarding "-Xcheck:jni"? I searched this site and nothing was returned.
Also, is there a way to initiate a thread dump when the process terminates? This would at least identify patterns when the process terminates.
