我应该从FindBugs中得到什么并发警告？

Question

我有以下代码：

import net.jcip.annotations.GuardedBy;
import net.jcip.annotations.ThreadSafe;

@ThreadSafe
public class Aoeu {
    @GuardedBy("this")
    private long aoeu;

    public long getAoeu() {
        return aoeu;
    }

    public void setAoeu(long aoeu) {
        this.aoeu = aoeu;
    }
}

从我读过的内容来看，FindBugs理解JCi​​P注释（事实上，1.3.9附带了它们），但我没有从上面的代码中得到任何警告。根据，我希望看到：

IS: Field not guarded against concurrent access (IS_FIELD_NOT_GUARDED)

This field is annotated with net.jcip.annotations.GuardedBy, but can be accessed in a way that seems to violate the annotation.

请查看下面显示错误的代码

class Test 
        {
            @net.jcip.annotations.GuardedBy("this")
            private int field;
            /**
             * 
             */
            public Test()
            {

            }

            /**
             * 
             */
            public void setField()
            {
                field++;
            }

        }
