It is true that agents can be mounted without the JDK; in fact, the JVM takes use of the Unix Domain Socket interprocess communication mechanism. Research before, I use the golang to write a small tool can directly attach agent jar to the target Java process without jdk, the tools is here : https://github.com/hengyoush/Java-Agent-Loader.
