test(s) should make following

1st test checks that sun/jdbc/odbc/ is missed in jre/lib/rt.jar.
It just checks physically that package is not included to rt.jar at all.

2nd test checks that it is not possible to make connection through ODBC using only standard JDK
This test tries to register a necessary driver. It should fail of course

The removed content from promoting documentation will be checked once manually.
