Can do storageClassConf.isEmpty() rather than calculating the length.
BTW. If it is empty you need not to attempt storageClass = StorageClass.fromValue(storageClassConf); and then land up with this Exception handling

Sounds good, much cleaner approach

LOG.info("Unknown storage class property {}: {}; falling back to default storage class",
STORAGE_CLASS, storageClassConf);
} else {
LOG.warn("Unknown storage class property {}: {}; falling back to default storage class",
STORAGE_CLASS, storageClassConf);
}
storageClass = null;
}
