@umesh do you use ScriptFeature in the scenario where the query cache fails? This is the only query in the ltr plugin that may perform a hashCode/equals on a mutable object.
Also when you said you returned false from isCacheable() you also had to do it from the ConstantScoreWeight returned from RankerQuery::createWeight ?

For me the scenario for this to happen would be:

you use named filters to do logging (using _name = 'ltr_query_log' on sltr) under a filter, this will force the query to be cached
when logging it'll reuse the same Query object but will populate the FeatureSupplier in LtrScript query causing hashCode to change (edited)
