My problem is the following: I want to make a hexxit server for my friends that I downloaded from technicpack.net, but when I click launch.bat it gives this error code:
Exception in thread "main" java.lang.ClassCastException: java.base/jdk.internal.
loader.ClassLoaders$AppClassLoader cannot be cast to java.base/java.net.URLClass
What can I do about this? I got the latest Java version.
