NetBeans 8.1 Fails to Check out from SVN - Error: E210004: Malformed network data

Hello,

Thanks a lot for your hint. I changed to CLI and the checkout worked fine. However, this is not a true solution, as it seems that CLI is no longer supported in NetBeans. See at
http://wiki.netbeans.org/FaqSubversionClients

"
However support for this client is outdated, we stopped supporting it when we started bundling the SvnKit and it works only as a backup client for users having issues with the previous recommended ones. Working with this client is the slowest you will probably suffer from major performance issues and new features or subversion commands (such as locking support) will not be available with this client. 
"

My SVN version is actually rather old: 1.4.2
So the problem cannot be that my SVN is too new.

I think SVNKit should be upgraded in NetBeans.

The question is how can I update it manually?

Thanks,
Peter
