Anand commented on GROOVY-7834:
-------------------------------

I am taking only lower and upper bound to generate hash code. Pairing function grantees the
output no to be deterministic. Have look at the pull request and let me know

> I believe the hashCode method is not overridden and it defaults to AbstractList which
iterates through all elements.  I don't think this should be the default behavior.
