      Description

      Stanislav Livotov wrote in SOLR-12688:

      ... LTRScoringModel was a mutable object. It was leading to the calculation of hashcode on each query, which in turn can consume a lot of time ... So I decided to make LTRScoringModel immutable and cache hashCode calculation. ...
