With Mojang making the move in the recent Minecraft 1.17 snapshots to finally bump the version of Java that Minecraft is built against from Java 8 to Java 16 any newer snapshots, 1.17 and all future releases of Minecraft will require Java 16 to work - they will not work at all with Java 8.
Up until now Java 8 has been the only version of Java we have provided, as that is what every version of Minecraft up to now has been built against and is the supported Java version for all Minecraft releases up to 1.16.5 - some softwares/server versions have supported other versions of Java, but Java 8 has remained the main supported version.

With the changes Mojang have made we now provide both Java 8 and Java 16 on all of our systems.
All jar list options running on Minecraft 1.16.5 and older are using Java 8 as they always have been - any jar list options running on Minecraft 1.17 or newer (and 1.17 Snapshot 20w19a and newer) will run on Java 16.

We now also have two separate Custom Server JAR options available for use - one for Java 8 and one for Java 16 - so you can choose which one you need or prefer for your setup. To use the Java 8 option, as before, your server jar needs to be named custom_server.jar - to use the Java 16 option your server jar will need to be named custom_server_j16.jar.

This also means that you can now use Java 16 on 1.16.5 and older options if you would prefer for any reason.
As an example if you are using the PaperSpigot 1.16.5 option right now, which is using Java 8, and wish to use it with Java 16 you would go into your server files and rename the paper_spigot_1.16.5.jar file in the jar folder to custom_server_j16.jar, then select the Custom Server JAR option on the jar list for Java 16 and when the page refreshes restart your server. PaperSpigot 1.16.5 will load the same as always, but using Java 16 instead (this can be done with any setup, just make sure it is compatible with Java 16 and that you rename the correct server jar).
