Review comment:
       I added a tab for JM in the [calculation spreadsheet](https://docs.google.com/spreadsheets/d/1mJaMkMPfDJJ-w6nMXALYmTc4XxiV30P5U7DzgwLkSoE). The changes aim to align the new derived heap size with the previous default heap size for standalone. As a result, the container size will increase a bit. `1472m` was miscalculated. It should be `1600m`.
