[Sitemap] Space added when formatting Number:Time with pattern %1$tH

[jlaur]

Given:

items/repro.items:

Number:Time Repro_Pattern "Pattern [X%1$tHX]" <time>

sitemaps/sitemaps.items:

sitemap repro label="Repro" {
        Text item=Repro_Pattern
}

Set value:

openhab:update Repro_Pattern "60 min"

MainUI:

But sitemap has a space added:

Expected Behavior

When using the provided pattern there should not be any spaces added.

Current Behavior

A space is added at the end. The same is true for the pattern %1$tH, for example. However, if both are used, space is only added after the first, so X%1$tHX%1$tMX will become "X01 X00X".

Possible Solution

Possible regression of #3644. See also openhab/openhab-webui#1953.

Steps to Reproduce

See description.

Context

This breaks formatting with state pattern %1$tH:%1$tM. For this specific pattern a work-around is to use %1$tR. This was fixed just in time for RC1 for the Miele@home binding: openhab/openhab-addons#15280, but other bindings (and user configuration) can easily be affected.

I did not observe this problem in 3.4.4, so it seems to be a 4.0 regression.

Fixed in RC1, probably same issue as fixed by #3708.
