reg license implications in implementing/using the JDBC spec

Hi,
I am trying to understand how far the pgsql-jdbc driver is compliant with
the JDBC-spec license. First couple of pages of the spec has license terms:

http://download.oracle.com/otn-pub/jcp/jdbc-4_1-mrel-spec/jdbc4.1-fr-spec.pdf
- clause(1) seems to grant license for evaluation purpose
- clause(2) seems to grant license for compliant implementations as
defined by (a)-(c), which has to be a fully compliant implementation which
can pass the JDBC-TCK.

As I understand, the pgsql-jdbc is not evaluation, nor is a fully compliant
implementation. Documentation also states, it has postgres specific
extensions to the spec.

With this, my Qs are:
1) Is pgsql-jdbc a legitimate implementation of JDBC-spec, conforming to
the JDBC license terms? If so, how?
2) Does postgres-JDBC Group obtained special license from
Oracle/jdbc-Spec-owner for this implementation of pgsql-jdbc.
3) Are users of pgsql-jdbc also considered violating jdbc-spec-license
terms, if pgsql-jdbc is not a legitimate implementation of the JDBC-spec.

thanks,
