Well, as I'm sure you understand, every developer has his/her own 
specific environment and preferred set of tools. It is not the goal of 
this mailing list to discuss how these _experimental_ feature are to be 
integrated inside IDEs. Since everything here has not been officially 
released, developers that want to chime in are bound to encounter some 
friction with the existing toolchain. While this is normally not a big 
issue for projects based on maven, ant or gradle (which can be pointed 
at the new JDK and will, more or less work), some work is required on 
the IDE side to allow you to create projects using those experimental 
features, and I hope you understand that we don't have much control over 
what IDE decide to do or support (esp. when it comes to experimental 
features).
