how to reproduce:

A.java

Class A {
   public static final String SCRIPT_1 = "return 1";
}

B.java

Class B {
    public static void main(String[] args) {
        System.out.println(A.SCRIPT_1);
    }
}

1. change A.java's constant to "return 2"; save and recompile.

only A.java is compiled, and run B still output
"return 1";

English is not my native language, so sorry for any mistakes.
