      Description

        When reading java.util.zip.ZipEntry:s from a zip archive, java.util.zip.ZipUtils.dosToJavaTime is called eagerly.

        This forces initialization of deprecated java.util.Date utilities early in the startup to evaluate values.

        In practice the VM typically never look at the ZipEntry.getTime(). Preliminary testing shows this can have a positive impact on startup and VM footprint.
