Java 17 Exception

[silvanheller]

When building & starting Cottontail on Java 17, an exception is thrown at startup (see below). This does not seem to impact performance or functionality as far as i can tell.

This is a Xodus issue and unfortunately, there is nothing I can do about it.

However, it will be fixed in a future version and indeed, it should not affect the functionality in any way. See XD-856
