      Description

        Over the course of the last two years, we've seen a more than 25% regression in build time. I've tracked this down to a handful of individual changes.

        On of them is JDK-8247872, which causes build time to go up with 24 seconds on my reference machine.

        The sudden increase in build time caused by JDK-8247872 needs to be analyzed, to see if it is possible to avoid.
