Re: [jdt-dev] multiple init of classpath containers

[Christoph Läubrich <laeubi@xxxxxxxxxxxxxx>]

Thanks for the feedback, I opened

 https://bugs.eclipse.org/bugs/show_bug.cgi?id=572869

as this is the first type I play around with classpath containers I 
can't tell if this changed recently.

That's also why I first asked on the dev-list to make sure I don't get 
anything fundamentally wrong maybe :-)
