That looks really horrible. It would probably be better to

   Collection<String> supportedItemTypes = profileType.getSupportedItemTypes();
   ...
   if ((!supportedItemType.isEmpty() && !supportedItemTypes.contains(itemType)) || ...) {

Why do you check profileType.getSupportedItemTypesOfChannel? A profile can change the item-type:

  • The timestamp update profile works with all channel-types (e.g. a humidity channel with supported item-type Number:Dimensionless) but can only be linked to DateTime items. So a check would fail (in fact, currently the profile does not provide information about accepted channel types, so this will not cause an issue, but in principle it could).
  • A profile could map numeric values to strings, so the channel would support Number, but the profile String. In this case you could never link them.

I agree that it looks horrible, but it was jut to "fit in" with the already existing code.

As to why I do the check, well it's because I did a global search for the interface methods and made sure both methods are called in all the places where one was called following an instanceof call.

I agree, the style was not good before either and if you want to keep it: ok. But the getSupportedItemTypesOfChannel is excluding valid combinations.

I'm definitely in favor of changing the code style here, but as always when I'm submitting a pull request, I try to limit my changes to the code logic, adapting to the local style I encounter.
I'll try to come up with a more sensible way of writing this up.
