Internal process for launching a main entrypoint of a class

Question

I am curious about the whole process behind the public static void main(args[]) launching in a Java class.

If some one could points me to some classes involved in the JDK code source ?

I want to know about the process in details.

I don't know where to start !

Answer 1

I believe here the main method is called (execution of CallJavaMainInNewThread method): src/java.base/share/native/libjli/java.c Line 2361

CallJavaMainInNewThread declaration: src/java.base/share/native/libjli/java.h Line 161

CallJavaMainInNewThread implementations for particular platforms:

• Nix: src/java.base/unix/native/libjli/java_md_solinux.c Line 741
• MacOs: src/java.base/macosx/native/libjli/java_md_macosx.m Line 739
• Windows: src/java.base/windows/native/libjli/java_md.c Line 719
