Research direction
The issue describes two separate problems: getopt incompatibility and ps L option behavior difference on MacOS. Investigate the current show busy java threads script at the repository root. For getopt, consider implementing manual argument parsing to avoid GNU getopt. For ps, find an alternative way to list Java threads on MacOS, possibly using jstack or other tools. Review comments in the issue for any existing solutions or partial patches.
