With the standard OpenCms WebDAV config, you can get a CmsVfsResourceNotFoundException error when accessing resources via WebDAV.
This is very annoying, because whenever you list the content of any __properties folder, OpenCms dumps 36 stacktrace loglines per file in that folder! If you scan your WebDAV dirs often during debugging (see note 1), these logs makes your life harder. (Of course, you could change the log level to something higher than INFO, but for me that's not acceptable.)
The issue is easily reproducible: point the browser to the opencms-exported webdav path, and click on any __properties dir.
I have found two workarounds, but I'm not really happy with any of them. Perhaps there is a better solution?
Notes
1 I'm debugging some OpenCms modules with NetBeans. I export their sources via OpenCms' WebDAV, and mount them in linux as davfs. If I add them to a NetBeans project, it automatically scans this mounted file hierarchy, resulting in OpenCms getting 'berserk' and beginning to overflow my poor console with useless traces. It gets worse, as NetBeans periodically re-scans these directories.
2 Setting the content-encoding property of every possible file and dir to UTF-8 does not help (the stacktrace claims it is missing).
My relevant environment and settings:
