mysql connector 6.0.2: "Column name pattern can not be NULL or empty"

I use liquibase and mysql-connector-java in my application, and I tried upgrading the mysql connector from 5.1.38 to 6.0.2. After the upgrade, liquibase throws an error when I try to run the migrations.

I'm calling the liquibase.Liquibase.update(String) method, and there's a long exception related to this line:

https://github.com/liquibase/liquibase/blob/liquibase-parent-3.4.2/liquibase-core/src/main/java/liquibase/snapshot/JdbcDatabaseSnapshot.java#L277

Here's the root cause of the stack trace:

The final parameter on that line is the columnNamePattern, and it is null. It turns out that the nullNamePatternMatchesAll connection property changed its default value between versions 5.1 and 6.0 of the connector. The default is true in 5.1, false in 6.0.

https://dev.mysql.com/doc/connector-j/6.0/en/connector-j-reference-configuration-properties.html

Workaround for me: I can set nullNamePatternMatchesAll=true in my connection properties. That makes the error go away.

Possible fix: Change liquibase to pass in "%" instead of null wherever it's currently using null to mean "all" (which assumes that nullNamePatternMatchesAll=true). The method I linked to is one. I have a feeling there are more.
