>          Issue Type: Bug
>          Components: jdbc
>    Affects Versions: 2.3.0
>         Environment: Apache Karaf, OSGi, Apache Derby, MySQL, PostgreSQL
>            Reporter: Ancoron Luciferis

> Currently, it is impossible to have a database table column defined as SQL standard type {{BOOLEAN}} (defined in SQL-99) automatically working with a {{java.lang.Boolean}} or {{boolean}} Java type.
> I am currently testing with:
> # Apache Derby 10.9
> # MySQL 5.6
> # PostgreSQL 9.3
> \\
> All three above databases support the column type definition. However, in the case of MySQL, it _magically_ works because the resulting datatype is {{TINYINT(1)}}, which is "compatible" with the data type {{bit}} (expected by current OpenJPA) - which makes it work by accident.
> For the other two databases, I get the following exception:
> {noformat}
> <openjpa-2.2.0-rUnversioned directory fatal user error> org.apache.openjpa.persistence.ArgumentException: "org.ancoron.jpa.test.TestEntity.set" declares a column that is not compatible with the expected type "bit".  Column details:
> Full Name: t_test.C_SET
> Type: unknown(16)
> Size: 1
> Default: null
> Not Null: false

> Of course, I have applied a workaround using custom Dictionaries, but the main point is that this makes my JPA-only application use implementation-specific configuration, which JPA is supposed to avoid.
> Running with EclipseLink instead of OpenJPA works as expected.
