Throws NoClassDefFoundError on mariadb jdbc driver when server shutdown about husksync HOT 1 CLOSED

This seems to be caused by CustomFishing and isn't something fixable by me unfortunately.

Specifically, CustomFishing is using its own LibraryLoader (based on Lucko's helper) to load runtime dependencies:
https://github.com/Xiao-MoMi/Custom-Fishing/blob/main/plugin/src/main/java/net/momirealms/customfishing/libraries/libraryloader/LibraryLoader.java

One of which is the standard MariaDB Java driver:
https://github.com/Xiao-MoMi/Custom-Fishing/blob/main/plugin/src/main/java/net/momirealms/customfishing/CustomFishingPluginImpl.java#L219

HuskSync uses Spigot or Paper's built-in MavenLibraryResolver to load this driver:
https://github.com/WiIIiam278/HuskSync/blob/master/paper/src/main/java/net/william278/husksync/PaperHuskSyncLoader.java#L43-L53

The way in which CustomFishing is downloading this library is truly bizarre. It seems to be downloading, then - at runtime - relocating the library. This causes a conflict with HuskSync's (correctly) downloaded library through the standard API provided by Paper // the Spigot runtime library resolver.

Please contact the author of CustomFishing to ask them to reevaluate the way their plugin loads libraries - as it isn't compatible with Paper Plugins and the new Paper runtime library loading API. If you need further HuskSync support, open a ticket and get in touch :)
