@Override
    public void run() {
      SearchLoadAndWriteProcessor processor = SearchLoadAndWriteProcessor.getProcessor();
      processor.initialize((LocalRegion) region, "key1", null);
      NetSearchRequestMessage message = new NetSearchRequestMessage();
      message.initialize(processor, region.getName(), "key1", 1500, 1500, 1500);
      message.doGet((ClusterDistributionManager) region.getDistributionManager());
    }
The Clear operation during a NetSearchMessage.doGet() in progress can cause DiskAccessException
by accessing cleared oplogs and eventually destroy region. The Test verifies that fix prevents
this.

<p>
Test must be DistributedTest because it requires ClusterDistributionManager.
