Java Compilers
Some time ago I've searched over NET for java compilers, then without good results,
Now I've found some:

https://commons.apache.org/proper/commons-jci/

jci seems tom be the winner, trough is a bit outdated.

 

 

Isn't there that commercial Java compiler also that compiles to native code? I think its located here: https://www.excelsiorjet.com/

You should add it to the list.

Seems you can use this code directly from java:

        String fileToCompile = "/Users/rupas/VolatileExample.java";

        JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();

        int compilationResult = compiler.run(null, null, null, fileToCompile);

        if (compilationResult == 0) {
            System.out.println("Compilation is successful");
        } else {
            System.out.println("Compilation Failed");
        }
