Description

      reloadedStoreFiles = loadStoreFiles();
      return StoreUtils.hasReferences(reloadedStoreFiles);

The intention of obtaining the HStoreFile's is to check for references.
The loaded HStoreFile's should be closed prior to return to prevent leak.

I noticed the increase in open files when running test suite. After checking recently modified code, I came to this particular method.
