DERBY-6213: Deprecate support for Java 5 and CDC

Fix build break when j15lib is defined. The classes in the
org.apache.derby.jdbc package now implement the JDBC 4 interfaces, but
they are still compiled against the JDBC 3 libraries, which don't
include all necessary classes. This patch makes them compile against
the JDBC 4 libraries instead.
