Description
"verify_lookup_length" is defined in BasicHashtable<F>, and it's called by "verify()" methods in: ProtectionDomainCacheTable : Hashtable : BasicHashtable Dictionary : TwoOopHashtable : Hashtable : BasicHashtable SymbolEntryTable : Hashtable : BasicHashtable ModuleEntryTable : Hashtable : BasicHashtable PackageEntryTable : Hashtable : BasicHashtable PlaceholderTable : TwoOopHashtable : Hashtable : BasicHashtable where "SharedDictionary" is the only class extending "Dictionary". "verify_lookup_length" uses "_lookup_count" and "_lookup_length" fields defined in BasicHashtable<F>, but the only class actually using those fields is "SharedDictionary", in all other cases they are not used, so "verify_lookup_length is a NOP for all the cases except "SharedDictionary".
