Re: [eclipse.org-architecture-council] Encourage projects to use JDT nul

[Lars Vogel <lars.vogel@xxxxxxxxxxx>]

Hi Marcel,

which project uses these annotation already?

Before advicing all Eclipse project to use these annotations, I agree
that we in Platform and JDT should start using them. (I assume that
this is currently not the case, I might be wrong here). Our Bug for
this is https://bugs.eclipse.org/bugs/show_bug.cgi?id=472631.

Best regards, Lars
