Openfire 3.4.5 throws an exception at session details

I’m running Openfire 3.4.5 and found it throws a hard java exception when you click a session in the administration web interface, if that session has been closed since the last refresh of that page.

I suggest a more “use friendly” page to be shown in this case, as it’s proabbly a relatively common thing to happen…

The exception is:

Exception:

java.lang.NullPointerException
