When loading archive regions in G1, it always uses the regions at highest addresses for CDS archives, committing regions as needed.
Since the Java heap is allocated from lowest to highest, this results in more memory than -Xms used by G1.
This is day one behavior, not sure if that has been intended, so starting off with an RFE.
