Konrad Windszus commented on SLING-9555:
----------------------------------------
bq. This change is not breaking any implementor of that interface
You cannot know. If some implementor has created a field with the same name
already in a subclass of {{ResourceChangeListener}} it may break!
I will therefore move the constants to another class.
> Define ResourceChange.ChangeType also as constant string values

> As all annotation values have to be provided as constants (e.g. in
> https://docs.osgi.org/javadoc/r6/residential/org/osgi/service/component/annotations/Component.html#property())
> and conversion from {{Enum}} to {{String}} cannot be resolved at compile
> time all enum values of {{ResourceChange.ChangeType}} should also be provided
> as String constants.
> Something like this does not work
> {code}
> @Component(property = {
> ResourceChangeListener.CHANGES+"="+ResourceChange.ChangeType.REMOVED.toString()}
> )
> {code}
> Compare with https://stackoverflow.com/a/13253879.
