Could not pass event SleepSkipEvent to sleep-most v5.2.0

[64BitUniverse]

Describe the bug
This isn't impacting gameplay, but when going through logs it causes an issue. Whenever someone sleeps, the console puts out:

java.lang.NullPointerException: Cannot invoke "me.mrgeneralq.sleepmost.interfaces.IBossBarService.setVisible(org.bukkit.World, boolean)" because "this.bossBarService" is null

Hello @64BitUniverse
Thank you for reporting this issue. I see that you are not using the latest version of spigot. This is ofcourse not a problem as the plugin is supposed to support from 1.8 range.

The issue originates from the support check I built in the code. When bossbars (in the API) are not supported, I don't register the boss bar service. This is causing an issue as there are places in the code where I simply don't use it.

I will need to adjust my code a little bit so I don't have scenario's where the bossbar service is NULL.

Thank you for reporting this issue!

Kind regards

Quinten

Hello @64BitUniverse

This problem will now be solved in the next release. A more long term approach will be taken to improve the architecture.
Thank you for reporting and have a nice day!

PS: this ticket will be closed as soon as the plugin is released.

Kind regards

Quinten
