pre-commit hook is finding transaction author to be a 'random' number sometimes

Hi,

I have a pre-commit hook that runs svninfo author, and sometimes it
returns a number instead of the actual username.

The transactions are created by the java svnkit library, over svn://
protocol.

svnlook returns things like '1571020', or '0:' (inc. the colon!), or
'1571073', but most often works fine returning the real username that
we supplied to the svnkit API.

Is that transaction username provided entirely by the client, and
svnserve just trusts it? I'm trying to see if I should investigate the
client or server initially. We did just upgrade from javasvn 0.9.2 to
svnkit 1.1.0 recently, so this is a likely candidate.

We're now using svnkit 1.1.0 on the client side, and svnserve
1.1.4. (We realise that is very old, we're required by a vendor to
continue to use that server as they "do not support higher versions.")

Our pre-commit hook fails the transaction when the invalid username
appears, so the transactions are not committed to allow us to review
them now.

I'm posting in case someone has seen such a situation before or can
offer advice. I expect we should now allow the transactions to
complete, so we can look at what is written into the repository, and
we should cause lots of transactions so we might catch a bad one under
tcpdump to study the svn protocol conversation.

Thanks and regards,

 Nick
