inbox.close(false) appears to be thowing NonSerialiazable Exceptions

[ghost]

I'm using the basic mstor logic with version 1.0.0 of your maven mstor library, but it's throwing an Exception on, I believe, the inbox.close() method. Note: I am not doing any writing to the disk so this Exception is odd. I made, as an attempt, my class which calls your code "implement Serializable", but that did not help.

Here's the basic code:

Properties properties = new Properties(); properties.setProperty("mail.store.protocol", "mstor"); properties.setProperty("mstor.mbox.metadataStrategy", "none"); properties.setProperty("mstor.mbox.cacheBuffers", "disabled"); properties.setProperty("mstor.mbox.bufferStrategy", "mapped"); properties.setProperty("mstor.metadata", "disabled"); properties.setProperty("mstor.mozillaCompatibility", "enabled"); Session session = Session.getInstance(properties);

try { store = session.getStore(new URLName("mstor:" + pathToMboxFile));

        store.connect();
        inbox = (MStorFolder) store.getDefaultFolder();

        inbox.open(**Folder.READ_ONLY**);

        Message[] messages = inbox.getMessages();

        int bodyPartCount = 0;

        // ***********************
        // process all mbox data.
        // *************************

        for (int pos = 0; pos < messages.length; pos++)
        {

          // processing.
         }

catch (NoSuchProviderException e) { log.debug("MboxController NoSuchProviderException Exception: " + e.getMessage()); } catch (javax.mail.MessagingException e) { errors.append(e); log.debug("MboxController MessagingException Exception: " + e.getMessage()); } finally { // close the mbox store try { inbox.close(false); store.close(); } catch (MessagingException e) { log.debug("MboxController Closing Store Exception: " + e.getMessage()); } }

Now, although the code does work and returns the mbox text and closes the file, when the inbox.close(false) runs, I get this error stack (or something close to it) each time in the Tomcat log:

Does your MessageInputStream class need to implement Serializeable?

Not sure what to try so I would appreciate your suggestions.

Thanks,
