Encoder fails on java.util.LocalTime

[kirillkh]

I'm using postgresql-async indirectly through vertx-jooq with MySQL 5.7. The issue I'm seeing is when trying to encode a WHERE clause that compares a database TIME field with a java.util.LocalTime value. I'm currently working around it by converting the value to java.sql.Time, which works fine, but is inconvenient. Stack trace:
