That said, we probably shouldn’t make decisions based on a single anecdote or assumptions about JVM configurations. What if a user runs Polaris on their own JVM and it breaks? That scenario is very likely. And what if a future JVM introduces a breaking change? Do we need to worry about that now? Probably not. It feels like a premature optimization at this stage. -- This is an automated message from the Apache Git Service.
