fixed static instance reference issue

[zcbbpo]

public class StaticInstanceReference {

    private static A a = new A();

    public void staticMethodReference() {
        //consumesRun(() -> a.doIt());
        consumesRun(a::doIt);
        //A b = new A();
        //consumesRun(b::doIt);
    }

    private void consumesRun(Runnable r) {
        r.run();
    }

   public static class A {
        public void doIt() {

        }
   }
}

修复类似这种静态实例的方法引用

是否还存在其他场景的方法引用呢
