if the NVMe partition was already formatted as "swap" then the service script would refuse mounting it; it would only format and mount a partition with an empty FS_TYPE. This causes such an instance to come up with only the 6GB swapfile swap which causes the Java VM launched with excessive amounts of heap space to simply crash
