I appreciate Substrate VM currently lists Method Handles as not supported and I suspect the following exception, which could be found in various issues is due to this reason:

Error: com.oracle.graal.pointsto.constraints.UnsupportedFeatureException: Invoke with MethodHandle argument could not be reduced to at most a single call

Is this a limitation by design that cannot be overcome or would it be possible to fix this problem with at least a workaround, if not a complete solution?

For example, I'm seeing this error when trying to build a native image of a simple application that uses Lucene , due to some core classes of Lucene,

This means Lucene and ElasticSearch won't be candidates for native images. I can see what a large (and great!) piece of work Graal is, it would be good to know if some limitations are bound to stay due to design.
