Maven Resource filtering bug - Dual Start

Hi guys,
I've got the following situation:

1.) A (embedded Jetty) Start class to start my webapp project.
2.) An application.properties file that gets filtered with maven properties, depending on the active profile

e.g. jdbc.username = ${jdbc.username} and in my pom.xml the according <properties><jdbc.username>....</jdbc.username></properties>  settings.

Now, in Maia 10666-10762 (and probably other Maia EAPs before), whenever I try to run my webapp via the Start class for the *first* time, Idea does *not* filter my application.properties. However, when I run my application for the *second* time, Idea correctly filters the resources. So whenever I make some code changes, I have to restart my application twice ;l(

Is this a known bug?

Cheers!
