[JGit] Push to new Amazon S3 does not work? ("funny refname")

[Daniel Cheng <j16sdiz+freenet@gmail.com>]

Pushing to new Amazon S3 repository does not work.
It say "funny refname" without pushing anything:

<<<<<<<<<
$ jgit push s3 master
To amazon-s3://0NQ4APQ8R7S6HQ65TWR2@egitsdiz/1.git
 ! [remote rejected] master -> master (funny refname)
$ s3cmd la
         DIR   s3://egitsdiz/1.git/
$
>>>>>>>>>

Any idea what's happening here?


The code is in WalkPushConnection.java line 137:
<<<<<<<<<
134    final List<RemoteRefUpdate> updates = new ArrayList<RemoteRefUpdate>();
135    for (final RemoteRefUpdate u : refUpdates.values()) {
136        final String n = u.getRemoteName();
137        if (!n.startsWith("refs/") || !Repository.isValidRefName(n)) {
138            u.setStatus(Status.REJECTED_OTHER_REASON);
139            u.setMessage("funny refname");
140            continue;
141        }
>>>>>>>>>

u.getRemoteName() gives "master" here.
Removing  n.startsWith("refs/") would generate a bad `packed-refs`
file in later code.
I tried to fix this, but failed to do so without breaking GitSsh transports
