Hello

and that is I cannot start PaperMC with Java argument "-classpath" in Java OpenJDK 11 in Debian 10 I get the following error message:

mc@mc:~/mc# java -cp '/server/services/version/paper-1.16.4-318.jar:lib/*' io.papermc.paperclip.Paperclip nogui --world-dir worlds Patching vanilla jar... Unable to retrieve Instrumentation API to add Paper jar to ClassPath mc@mc:~/mc#

mc@mc:~/mc# java -version openjdk version "11.0.9.1" 2020-11-04 OpenJDK Runtime Environment (build 11.0.9.1+1-post-Debian-1deb10u2) OpenJDK 64-Bit Server VM (build 11.0.9.1+1-post-Debian-1deb10u2, mixed mode, sharing)

in Java 8 it went without problems

with the Java argument "-jar ..." it works without problems.

on newer versions of java, we use an agent to allow us to hook into the classloader to boot the patched server jar without breaking plugins, etc; You'll need to add the agent manually, or launch the server with -jar, pretty sure that works with -cp too, Launcher-Agent-Class: io.papermc.paperclip.Agent
