I keep encountering (during startup processing of rules)
2018-05-22 19:35:52.474 [WARN ] [essage.ApplicationUpdateMessageClass] - TODO: Implement Application Update Request Handling of New ID Assigned (64).
Not sure if that’s anything harmless or critical, just wondering as I haven’t seen it before and didn’t see anything in Github .
This is a ZWave log entry. This is nothing new, and it means that you’re system is receiving a message that the binding doesn’t handle.
Is that something really worth for a WARN message and to bother the regular user with it? I’d definitely prefer a DEBUG message in such cases unless something is malfunctioning and the user has a chance to correct it.
It could be reduced, but it has been this way for 3 years, so my point was it’s nothing to be worried about (to answer the question that was asked 
).
However, I do think it fits in correctly with the guidelines as this shouldn’t ever happen.
There are also some warnings for items with tags when you start a new instance and choose the Demo package in the “Initial setup”:

The warnings don’t show after restarting openHAB.
The Paper UI Control page logs a big error in the browser console when it is first loaded but it doesn’t seem to affect functionality:
I can’t seem to change the volume of radio stations via the Basic UI of the Demo sitemap. It logs warnings for this:

I finally installed 2.3.0.RC1-1 on a clean rPi3 and started testing it
So far (without any configs/addons): it works fine 
(more testing results soon)
Thanks - should be fixed with Fixed handling of IRRADIANCE unit by kaikreuzer · Pull Request #5602 · eclipse-archived/smarthome · GitHub.
I get this in the last few builds:
2018-05-23 07:20:52.826 [WARN ] [rm.AbstractFileTransformationService] - Could not transform 'NULL' with the file 'beaufort.scale' : Scale can only be used with numeric inputs
Any way to get rid of that.
Also I get a lot of:

At start up just after the items files loading.
Is there a way to get the transforms to load before the items?
This will also occur after saving an .items file with tags in it, while OH is running. The warnings are gone after an OH restart.
Both fixed with fixed small issues in demo files by kaikreuzer · Pull Request #715 · openhab/openhab-distro · GitHub.
Not sure how to fix this. Could you enter an issue at ESH for it, please? If anyone has an idea how to fix it, please do so - if not, it should be ok to leave it as is for the release if it does not have any functional impact.
Could you please enable this debug logger:
log:set DEBUG org.eclipse.smarthome.core.audio
and post the resulting exception (which will then be logged next to this warning)?
What platform are you running on?
(Likely) same problem for me. Running on Pi3 with Zulu java 1.8.0_152-b76, I have been having to use alsa tools to (statically) set volume. I think it used to work long ago when I was still using Oracle java but can’t tell for sure.
EDIT: However, according to this, the same provlem happens on x86 and Oracle Java.
Calling setMasterVolume(float) gives

I have some problems with linking items to a channel in PaperUI. I clicked on the blue button to link a channel in the Configuration -> Thing section, selected “Create new item”, confirmed it by clicking on “Link”. Popup remained open and nothing happened. The Item has been created in the background but the link didn’t establish.
Some more errors in the browser console - missing files / icons - and a dupes check after entering the Configuration -> Items section.
Innogy smarthome binding is not working in RC1. OH2 with installed binding is not starting up, removing cache and tmp folders also does not help. After removing the binding from addons.cfg and trying to reinstall the following error messages are displayed:

No, but reduced logging level and moved exception handling one level up by kaikreuzer · Pull Request #5603 · eclipse-archived/smarthome · GitHub should remove those warnings from the log.
Thanks, excellent finding! Should be fixed with https://github.com/openhab/openhab2-addons/pull/3585.
