Missing '}' flagged by LSP4MP validation for property referencing inner class name

[scottkurz]

From the 'guide-microprofile-reactive-messaging' guide, we have in microprofile-config.properties:

mp.messaging.outgoing.systemLoad.value.serializer=io.openliberty.guides.models.SystemLoad$SystemLoadSerializer

which gets flagged with the error:

[scottkurz]

mp.messaging.outgoing.systemLoad.value.serializer=io.openliberty.guides.models.SystemLoad$SystemLoadSerializer

This use of an "inner class" as property value is getting flagged as an error by Liberty Tools validation, based on the LSP4MP code.

If I look at the Git history in the LS project:
eclipse-lsp4mp/lsp4mp@8512c09
In many MicroProfile implementations, ${other.property} can be used to refer to the value of an already defined property when defining the value of another property.

Does Liberty support something like prop1=${prop2}?
