> We find TestLruBlockCache#testBackgroundEvictionThread fails occasionally.
> I think it's a problem of the test case.
> Because runEviction() only do evictionThread.evict():
> {code}
> public void evict() {
>       synchronized(this) {
>         this.notify(); // FindBugs NN_NAKED_NOTIFY
>       }
>     }
> {code}
> However when we call evictionThread.evict(), the evictionThread may haven't been in run()
in the TestLruBlockCache#testBackgroundEvictionThread.
> If we run the test many times, we could find failture easily.
