Issue Description: Server startup hangs on "Updating database schema from version = 4".

• Dynmap Version: Dynmap-3.4-beta-2-spigot.jar
• Server Version: Paper version git-Paper-242 (MC: 1.18.2)
• Pastebin of Configuration.txt: https://pastebin.com/Lxqhezza
• Server Host (if applicable): apexminecrafthosting.com
• Pastebin of crashlogs or other relevant logs: https://pastebin.com/TuBzReQN
• Other Relevant Data/Screenshots: I'm using a map from minecraft 1.18.1 and besides dynmap there is Chunky v1.2.164, WanderingTrades v1.7.1, LuckPerms v5.4.9
• Steps to Replicate: I have not gone to the length of replicating it yet since I did not wan't to risk corupting my dynmap database yet. Since I do not know what the inner workings are of this step where he is stuck I was not yet willing to stop it. And I belive it's a incredible data set to download to actually try to replicate it locally.

[x] I have looked at all other issues and this is not a duplicate
[ ] I have been able to replicate this

For the next time it should have an option to do this in parallel while the server is opened.

That sadly is not possible iirc, as dynmap needs the storage to work

that is not a bug, it just needs to update the database, which if having a huge map, takes a long time

Hmm, I think still something went wrong. It after waiting a while it just killed dynamo and continued starting the server. When it was fully started dynmap didn’t work. I’ll send a update from the log file at a later moment.

after a few tries though it worked so I don’t need more support on this but I will leave the log file for completeness if I get to it.
