Simplify method CollectionUtils#isEqualCollection

@StudentGu

Thank you for your PR.

I removed some duplication in CardinalityHelper and the class now reuses the existing HashBag class, see CollectionUtils.CardinalityHelper.equals(Collection<?>, Collection<?>):

commons-collections/src/main/java/org/apache/commons/collections4/CollectionUtils.java

Lines 66 to 68 in 3f7cb39

	static boolean equals(final Collection<?> a, final Collection<?> b) {
	return new HashBag<>(a).equals(new HashBag<>(b));
	}

This PR can be closed IMO.

Thanks! @garydgregory
It is a great pity that I don't have an jira account now.
I have applied to the community for an jira account through https://selfserve.apache.org/jira-account.html and select the commons-collections, but there has been no reply.
Could you help me deal with it?

@StudentGu
All you have to do to get a Jira account is apply. The application form exists to avoid bots from creating tickets and spam which was a problem in the past.
