Re: [tycho-user] When can we expect a Java9-ready Tycho release?

I agree Java 9 support is an important feature.

I prepared a commit to use JDT from Oxygen 1a

Unfortunately looks like it's not that easy.
We have to use Java 9 for compiling Tycho as JDT now requires Java 9.

Compilation of this patch using Java 9 currently fails with errors like

[ERROR] The type java.lang.String cannot be resolved. It is indirectly referenced from required .class files

so we are back to the original issue reported in

maybe I'm missing something obvious here?
Could use some advice from JDT experts.

    JDT compiler is fully ready for Java 9 as of Photon M3/Oxygen 1a. It may miss a few features related to other Java 9 stuff, but compiler is already ready.
    So I think it would be great if Tycho could be ready for Java 9 asap by pulling newer JDT bundles, as there is already value for many users in it. Some RCPs do include a JVM directly, and might already prefer using, buiding on top of and shipping Java9 for
     several reasons such as performance or to easily tailor the JVM for their apps; and those RCP are most likely using Tycho. So I see a huge value for the community in shipping Java 9 compilation support soon.
    That said, I believe Tycho typically waits for JDT milestones to be ready before consuming them, doesn't it? According to <> , Photon M3 will be shipped on Oct 27th.
