I am working on a small project for a client. Today I started to get this error. What things cause this error?  Everything was working fine 2 days ago. Today. It throws the error below every time I try to fetch emails. It does the same thing using the sample "email client" file that came with the plugin.

 

java.lang.ArrayIndexOutOfBoundsException

 

I do believe my laptop install some updates last night. But I don't see any that would appear to have affected java. But I can't confirm that for certain.

update: I uninstalled all the updates that were installed last night...still having the issue.

Another update. Tweaked a few things. I have it working on every mailbox, except the inbox. I can't figure out why it's throwing the error on the inbox.

Got it working. Apparently the "UID" of some of the mailboxes changed. I don't totally understand why they changed, but at least I can address that. And get the thing working.
