Describe the bug

First boot with worldguard-bukkit-7.0.4.jar in the plugins folder succeeds:

• a plugins/WorldGuard/ directory is created.
• The plugin works in game.

When restarting however, the whole server crashes during initialization of WorldGuard.
The log file reports:
//first, a whole lot of log lines
[Server thread/INFO]: [WorldGuard] Enabling WorldGuard v7.0.4+f7ff984
//after previous line: nothing.... The server has crashed. (This line is of course not a part of the log)

A java crash dump is created. Here is an extract:

So there perhaps (?) seems to be a problem with an SQLite profile cache when enabling WorldGuard if the cache "file" already exists..?

Important info

If I remove worldguard-bukkit-7.0.4.jar from the plugins folder and start once again, the server does not crash. upon booting. However WorldGuard does not seem to be installed at all (even though the plugins/WorldGuard directory remains untouched by me). Putting the jar back once more makes the server crash when booting again. Removing the plugins/WorldGuard directory and restarting works as in step 1+2 below.

To Reproduce

1. Install by putting jar in plugins folder
2. Start server. It works. WorldGuard creates directory and works in-game.
3. Stop server.
4. Start server again. The server crashes when trying to initialize WorldGuard

Expected behavior
On step 4 I expect the server to recognize that WorldGuard is installed and that the server does not crash.

not a WG issue, something between sqlite (provided by the server) and whatever jank-ass jdk freebsd ships.

Thank you for your quick response. By "server" I assume you mean PaperMC and this should be reported them, or maybe even a report to "jank-ass" OpenJDK.
