      Description

        Currently both Jar and Jmod collect file lists using File.list() and Files.walkFileTree(). Both of these have no defined ordering according to the Java spec, but also the current implementation of these methods falls through to OS file system I/O calls, whose ordering is non-deterministic and typically dependent on CPU architecture (eg.AMD differs from Intel).

        This enhancement will enable us to produce "reproducible build" Jars and Jmods.
