Fix introduces a minor change to JSON messages send from DB to VS adapter.
SELECTs to Virtual Schemas created prior to Fix Versions could fail with error mentioning "org.glassfish.json.JsonObjectBuilderImpl$JsonObjectImpl.getBoolean".
To avoid these errors, either run ALTER SCHEMA REFRESH after DB update or prior to update install a Virtual Schema JAR based on "virtual-schema-common-java" 14.0.5 or newer. E.g., for PostgreSQL Virtual Schema it's release 4.0.2 and respectively file "virtual-schema-dist-14.0.5-postgresql-4.0.2.jar".
