Hi, stumbled on a nasty bug in Clojure. I'm transferring Clojure objects around using java serialization. When de-serializing a List (clojure.lang.ASeq) it has a hashCode of 0. This means lookups for the object in HashMaps PersistentHashMaps HashSets etc fail. The pre-serialized version of the object has a valid non-zero hashCode.
The reason for this is that the cached hashCode value is marked as transient and its default un-cached value is -1. E.g. if he hashCode is -1 compute the hashCode. Of course when an Object is de-serialized any integer transient fields are set to 0. This bug seems to be in all Clojure versions. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
