"mvn liquibase:diff" does not find any differences between databases

Since the fix for issue was introduced in Liquibase 3.2.1, diffing databases using Liquibase Maven Plugin always gives empty result, even when there actually are differences between databases.

For example, I have two databases, one which contains a table named "DUMMY", one which doesn't. When I run "mvn liquibase:diff" using Liquibase Maven Plugin 3.1.1, I get the following correct result:

When I change Liquibase Maven Plugin version to 3.2.1 or 3.2.2, I get this incorrect result:
