change modifiedCount to type long

[danibs]

modifiedCount should be long instead of Long. If not:

public long getModifiedCount() {
    return modifiedCount;
}

could throws exception.

NOTE: The public int hashCode() method must to be updated accordingly

Hi @danibs thanks for the PR.

Apologies for the delay in responding. I have opened JAVA-5621 to track this and will triage it shortly.

All the best,
