I haven't pasted the exception message since I am confused why my Eclipse
couldn't stop at the generic Exception and goes directly to finally. Or
maybe my eyes are too tired.
The exception is caught here, inside
org.apache.james.core.MimeMessageWrapper
----------------------
private synchronized void loadMessage() throws MessagingException {
if (message != null) {
//Another thread has already loaded this message
return;
}
InputStream in = null;
try {
in = source.getInputStream();
headers = new MailHeaders(in);
ByteArrayInputStream headersIn
= new ByteArrayInputStream(headers.toByteArray());
in = new SequenceInputStream(headersIn, in);
message = new MimeMessage(session, in);
} catch (IOException ioe) {
System.out.println(ioe);
throw new MessagingException("Unable to parse stream: " +
ioe.getMessage(), ioe);
} catch (Exception e) {
System.out.println(e);
e.printStackTrace();
} finally {
IOUtil.shutdownStream(in);
}
}
-------------------------
But it doesn't stop at the breakpoints I set at
throw new MessagingException....
and
e.printStackTrace....
but it stops at IOUtil.shutdownStream(in);
----------------
I add
} catch (Exception e) {
System.out.println(e);
e.printStackTrace();
in case it is other exception, but it was not caught here.
-----------------
I will try your suggestion.
