Automatically register unknown devices

hi! I try configure Automatically register unknown devices my config:

<entry key='database.ignoreUnknown'>false</entry>
<entry key='database.registerUnknown'>true</entry>
<entry key='database.registerUnknown.defaultCategory'>Default</entry>
<entry key='database.registerUnknown.defaultGroupId'>2</entry>

I find small bug. If my deviceid contain dot, for example "ggg.ggg.ggg", in logs I have error:

without dots new device creating without log entries
update location for devices with dots in deviceid works correctly

You're probably missing database.registerUnknown.regex.

What syntax for it? I can write

'\.*'

?
