Getting a NPE when calling the getContent of a multipart message

Question

Hi,
I get a NPE when I try to get the body of a multipart MIME message. The BODYSTRUCTURE returns the number of bytes of a bodypart before any decoding is done, the getContent then expects server to return that many bytes when it does something like "aa fetch 1 BODY[0]<0.16384>", when the server does not return anything a NPE is thrown. The exception is as follows
java.lang.NullPointerException

     at com.sun.mail.iap.Response.<init>(Response.java:32)

Did anybody see this exception ?

I get this error too when:
Part part = message;      
while(i < path.length && part != null) {
MimeMultipart multipart = getMultipart(part);
if (multipart == null)
     throw new IOException("not multipart.");
part = findPart(multipart, path);     
i++;     
if (part == null)
throw new IOException("not a part of message.");
InputStream in = part.getInputStream();
int b = 0;
while((b = in.read()) != -1)
out.write(b);
at part.getInputStream() i get:

Any resolution to this yet?
It worked up until I changed to an SSL connection to IMAP.
Could this affect at this level?
Help appriciated.
