FindBugs应该期待什么样的并发警告？

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，FindBugs的理解JCi​​P注释（事实上，1.3.9船舶与他们），但我没有得到从上面的代码的任何警告。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.

请检查下面的代码则显示错误

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

      } 

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

     }
