Getting a reference to the class we are working with fails [message #949878]

In the following construct I expected structClassRef shouldn't be null:

acceptor.accept(structDef.toClass(structClassName)).initializeLater [
    documentation = structDef.documentation
    val structClassRef = structDef.newTypeRef(structClassName)
    ...
]

since it's only called after indexing and after a class with this name is registered. But as it happens, I _do_ get null here sometimes. What am I misunderstanding?

What do you mean by 'sometimes'?

Please note that the structClass is available under the local name 'it'
so it may be easier to put that one into a newly create
JvmParameterizedTypeReference.setType(it)

It now looks like the problem happens when I try to do anything with cross-references outside initializeLater block (which I was doing to eliminate some duplication).
