Is there a way to get notified when a method from a Different JVM is called.
Dev Env: JDK8, Windows 10 (later on cloud for deployment).
I have couple of Java applications running, One in App Server and another is standalone batch process.
Whenever a core java class method is called on either of these JVM's e.g. PrintStream.print, I need to get handle to input string and log it somewhere else.
I tried with 1. Java bytecode manipulation libraries e.g. Javassist, to transform byte code using Instrumentation, but it allows to have handle and manipulate User Defined classes / Third party library classes only - not java., sun. etc... (even if we do it somehow, it says - it violates JRE binary licence - Official Javadoc says this process of instrumenting the rt.jar class violates the JRE binary code license - so this may not be the go ahead approach. https://docs.oracle.com/javase/8/docs/technotes/tools/windows/java.html )
Reflections - Can be used when you are on the same JVM, not sure if it works on different JVM.
Appreciate suggestions.
