Re: [Jamvm-general] Can JamVM optimize away static branches?

[David G. <dav...@gm...>]

The javac compiler optimizes them away before JamVM even gets a look in:

$ cat foo.java
public class foo {
    static final boolean DEBUG=false;

    public static void main(String[] args) {
        if (DEBUG) {
            System.out.println("hello");
        }
    }
}

$ javap -c foo
Compiled from "foo.java"
public class foo extends java.lang.Object{
static final boolean DEBUG;

public foo();
  Code:
   0:   aload_0
   1:   invokespecial   #1; //Method java/lang/Object."<init>":()V
   4:   return

public static void main(java.lang.String[]);
  Code:
   0:   return

}

Cheers,

Dave
