Hey, thanks for your tips!
I could change the vaulue in the class.
I found it fast, as it was the first variable and changed it to 1000 for testing purposes. Saved it and put it back into the jar with WinRar in zip mode and normal compression.
But when the server starts up, this error shows up

Thanks in advance, if you can help me!
