JavaHL: redirect cycle detected for non-cyclic redirects

[Marc Strapetz]

I have following Apache virtual host configuration which contains a 
redirect:

  RedirectMatch 301 ^/svntest/(.*)$ /svntests/$1
  <Location /svntests>
    DAV svn
    SVNParentPath /misc/svntests
    ...
  </Location>

When trying to access a redirected repository from command line, this 
works fine:

$ svn ls https://host/svntest/test1
Redirecting to URL 'https://host/svntests/test1':
project1/

When trying to access using JavaHL, a "Redirect cycle detected for URL" 
SubversionException is thrown. Code snippet:

RemoteFactory remoteFactory = new RemoteFactory();
remoteFactory.openRemoteSession("https://host/svntest/test1";, 100);

As the definition is not cyclic and retryAttempts=100 should be 
sufficient, it looks like there is a JavaHL problem related to redirects?

Tested with Subversion 1.9.5
