        Description

        We've found that when building Zero on s390 (note, NOT s390x), the set max heap settings during a build can be problematic. Sometimes builds failed, because the heap couldn't be allocated. It's currently set to 1100M (JDK 8) and 1024M (JDK 9+) which isn't always available on every builder. Our experience has shown that building with the following big workload settings works well:
        -Xmx768M -Xms256M
