[Homematic] Binding 4.2.2 GATEWAY-EXTRAS does not load/refresh if systemvariable type string has special content

[grmpf72]

Expected Behavior

If the binding is scanning (new) things, GATEWAY-EXTRAS should be there no matter what the content of any string-variable is
A refresh should refresh all variables no matter what the content of any string-variable is

Current Behavior

I do have a fresh installation of Homematic Raspberrymatic 3.77.7 and openhabian 4.2.2.
No additional bridges within HM and in openhabian only homematic binding has been added.
After the initialization/scan the GATEWAY-EXTRAS thing is missing if a following systevariable in HM exists:
Name: doesn't matter
type: string
content: >= 11 numbers

event.log warnings:
2024-10-16 16:48:22.465 [WARN ] [ternal.handler.HomematicThingHandler] - For input string: "12345678901"
2024-10-16 16:50:41.946 [WARN ] [ternal.handler.HomematicThingHandler] - For input string: "1234567890123"
2024-10-16 16:54:20.773 [WARN ] [ternal.handler.HomematicThingHandler] - For input string: "-12345678901"
2024-10-16 16:55:13.529 [WARN ] [ternal.handler.HomematicThingHandler] - For input string: "+12345678901"

-> although it is only a warning no variables are refreshed!
-> If the variable exists before the binding ist installed, GATEWAY-EXTRAS thing will not be found!

If the variable contains a letter everything works fine. If it is shorter and contains only number it's also ok.
E. g. works with:
-1234567890x
+1234567890x
x1234567890x
111
12345678901xyz

Possible Solution

change the content of the variable :-)

Steps to Reproduce (for Bugs)

Easy! See description above. Just add a string variable wir 11 digits and see wether GATEWAY-EXTRAS can be refreshed!
