[Exist-open] Java client shows no collections. Lock failure error messages, etc
|

When I start the java client it shows no collections. But I can navigate
to collections and subcollections from the command line, as long as I
don't try to go back to root level. If I do that the client hangs for a
very long time.
I assume this message in exist.log is relevant:

There are also messages from one of the apps using eXist. The app seems
to work fine, though:

Any ideas about what is wrong?
I use version 1.1.1-20061024.
