Confluence cannot start when Bandana-Config contains wrong POP-mail-password

I recently configured a space-pop-mail-account but not knowing the password I left it "broken".

Now, due to an OutOfMemoryError (already reported at support.atlassian.com) I had to restart the Tomcat-server. This failed due to the exception below. It seems as if because of this wrong password Confluence won't startup at all. There should be a robust error handling so that I can at least change the password inside Confluence.

Workaround: Go to the <confluence-home>/config/<Space Key>-directory and edit the confluence-space.bandana.xml. As the password is clear-text I just had to enter the correct password. Perhaps an alternative is to completely delete the <popMailAccount>-entry.

And now here is the exception:
