@neykov I saw a problem if I modified `LocalManagementContext.getConfig()`
to do the resolution. If this method returns something that is not the original
`configMap` - even if it is an identical copy (such as by replacing the method
body with `return BrooklynProperties.Factory.newEmpty().addFrom(configMap);`)
then I got this exception during launch:
```

Interestingly if I modify the method to use a MemoizedSupplier - meaning
that it will consistently return the same object - the error disappears. This
suggests that there is something that gets upset if `getConfig()` returns a
different object, even if the contents are the same.
[A thought occurs to me. Is something *modifying* the config object that is
returned?]
