This looks like a nice straight forward cleanup/change. Thanks Claes.

> This is motivated by Jigsaw where URIs might be created unconditionally during startup, and this trivial patch is extracted from an experiment to address observed inefficiencies in java.net.URI[1]. Around half the improvement detailed in [1] can be attributed to this patch, while it does not impact compiled code performance.

Good to hear.
