Brandon Williams commented on CASSANDRA-16304:
----------------------------------------------
It's not abandoned, just inactive due to no need for modification... until now,
potentially.
> Consider implementing ClusteringComparator without a lambda

> Key: CASSANDRA-16304
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16304
> Project: Cassandra
> Issue Type: Improvement
> Components: Build
> Reporter: Adrian Cole
> Priority: Normal
> Fix For: 4.x

>
> Using lambdas forces jamm to do things that can easily break. It might be
> safer to implement things like ClusteringComparator directly as classes or as
> an enum
> {noformat}
> Unexpected exception during request
> (org.apache.cassandra.transport.messages.ErrorMessage)
> java.lang.UnsupportedOperationException: can't get field offset on a hidden
> class: private final org.apache.cassandra.db.ClusteringComparator
> org.apache.cassandra.db.ClusteringComparator$$Lambda$165/0x000000010028ab60.arg$1
