License on Persistent{HashMap,Vector} reverted to EPL?

[Michel Salim]

Hi all,

Daniel Spiewak recently tried to get his port of Clojure's persistent
vector into Scala:
https://lampsvn.epfl.ch/trac/scala/ticket/3724#comment:23

the link above pointed directly to the conversation thread where I
raised license concerns. It turns out that Rich relicensed the two
Java source files to BSD on 2008-11-13

http://github.com/richhickey/clojure/commit/2fb7a11de0332080286ae74ae6eccf8bf2749621

but PersistentHashMap is reverted back by Christophe Grand, with
Rich's sign-off, on 2009-08-24

http://github.com/clojure/clojure/commit/56d70e433a66087c720e82a67e6460fae1169862

and PersistentVector reverted on 2009-07-16
http://github.com/richhickey/clojure/commit/f2de9c79eb5978a6a81ad3d0994ec44f490e3152

To clarify,
1. are the changes intentional, and
2. presumably the BSD-licensed file versions are still safe to be used
by other projects for reimplementation
3. are there prior conversations, private or public, that I point the
Scala guys (and others) to, if this topic comes up?

Thanks,
