• Fix OpenJ9 issue - either by updating to latest async-profiler which claims to fix, or by always using Java profiling engine if OpenJ9 is detected
• Publish necessary modules to a Maven repository & ensure correct libraries are included
• Update spark-bukkit to gracefully handle things if installed on a Paper server
• Change from Bukkit to Paper in platform info
