[jira] Commented: (THRIFT-226) Collections with binary keys or values break equals()

["Nathan Marz (JIRA)" <ji...@apache.org>]

Nathan Marz commented on THRIFT-226:
------------------------------------

For the same reason set<binary> is just plain broken in Java. Set won't enforce that the a particular byte[] value appear only once.

> In Java, byte[].equals tests object equality, not value equality. As a result, if you have two list<binary> (or set<binary>, or map<binary, binary> with the same values and you do TBase.equals(), two structs that match by value won't return true. If we're going to do value equality, which I think we should, then we should make this consistent with collection types.
