Confirmed: I just started seeing this error after upgrading to Oxygen.

I can make that error go away, but then I just get this one instead:

So it looks like we have a major problem with the metamodel not being set up.

@davidfestal @FroMage I'm going to need your help here:

  1. in OSGi, what event is responsible for setting up the metamodel, and
  2. why might that be broken in Eclipse Oxygen?

It seems to be a race condition that could sometimes happen in previous Eclipse versions, but now happens systematically under Oxygen when starting Eclipse with a Ceylon project opened. The Ceylon meta-model is registered in a Job, and it happens that, now, the Ceylon classpath-container initializer of a project is indirectly called by the JDT initialization before the end of Ceylon meta-model registration. And some Ceylon classes are involved in the implementation of the Classpath-container initializer.

I'll try to provide a fix for this asap.

Thanks David.

This is not intermittent for me but happens every single time I launch/restart Eclipse on Linux and macOS.

Right, me too.

This is fixed, but at the cost of unnecessary binary builds on almost every startup. We need to come back and fix that.
