If those 'certain aspects' are tightly controlled
by you, I would suggest the following method.

<sscce>
/** Property dump for 'certain aspects of the program'. */
class EchoArg {

  EchoArg(String[] args) {
    StringBuffer sb = new StringBuffer();
    sb.append("java ");

    String libPath = System.getProperty("java.library.path");

    if (libPath!=null) {
      sb.append("-Djava.library.path=");
      sb.append(libPath);
      sb.append(" ");
    }

    String classPath = System.getProperty("java.class.path");
    if (classPath!=null) {
      sb.append("-cp ");
      sb.append(classPath);
    }

    sb.append( " " );
    sb.append( this.getClass().getName() );
    sb.append( " " );

    for (int ii=0; ii<args.length; ii++) {
      sb.append(args[ii]);
      sb.append(" ");
    }

    System.out.println(sb.toString().trim());
  }

  public static void main(String[] args) {
    EchoArg ea = new EchoArg(args);
  }
}
</sscce>

[Typical run]
C:\EchoArg>java -Djava.library.path=x -cp .;y.jar;z.jar EchoArg a b
java -Djava.library.path=x -cp .;y.jar;z.jar EchoArg a b

C:\EchoArg>java -Djava.library.path=f -cp .;g.jar;h.jar EchoArg p q
java -Djava.library.path=f -cp .;g.jar;h.jar EchoArg p q
