It is recommended to use the -XX:+EnableDynamicAgentLoading startup argument to hide the warning and stop any possible errors that may happen when applying the patch.
Features:
- Gets player skulls working again
- Stops those "Couldn't look up profile properties" spam errors
- Zero config (just drop it in your plugins folder)
- Runs on any server software (Assuming authlib is in the default path)
- Super lightweight
