Description

I'm surprised by this call to Iterator.remove() in org.apache.cassandra.db.compaction.antiCompactGroup: the iterator in question seems to come from org.apache.cassandra.db.lifecycle.LifecycleTransaction.originals(), which returns an unmodifiable set, so I would expect this call to always fail with an UnsupportedOperationException.
