After I started a minecraft server with 1.17 and now there seems to be some problems with the older minecraft versions. I have multiple servers all the way from 1.12 to 1.16.5 connect to a hub server. They use version jre-8u291. The new minecraft use Java 16 developer version to run. This means that my other minecraft servers wont start duo the java version is supportet. Is there any way I can write a line in the start bat file, that a specific java version should be used for older versions of minecraft servers? exsample of my start bat file. @Echo off title Server Console java -Xmx1024M -Xms1024M -jar ServerFile.jar PAUSE I hope there are some who have a solution for this problem.
