Java FileSystemPreferences errors
The container works great, even with multiple deployed, but I get the following on the console:
Mar 17, 2019 10:50:20 PM java.util.prefs.FileSystemPreferences checkLockFile0ErrorCode
WARNING: Could not lock User prefs. Unix error code 20.
Mar 17, 2019 10:50:20 PM java.util.prefs.FileSystemPreferences syncWorld
WARNING: Couldn't flush user prefs: java.util.prefs.BackingStoreException: Couldn't get file lock.
Doesn't seem to impact functionality, but still. Tried some Googling but nothing I could find is working (I may not have been doing it right though; new to docker).
Any ideas how to resolve it?
It doesn't have any effects from what I have seen so far so I never bothered to fix it. The app user probably just needs a proper home folder.
It's already listed in the issues section though.
Hi, on my system it gets additional to the missing file lock:

Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?
The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval. It should work with any VNC viewer. Try it by running:
x11vnc -ncache 10 ...
One can also add -ncache_cr for smooth 'copyrect' window motion.
