> Project: HBase

>
> 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.
