Trivial Description
org.apache.derby.client.am.Statement defines three constants, CLOSE_CURRENT_RESULT, KEEP_CURRENT_RESULT and CLOSE_ALL_RESULTS, that are also defined in java.sql.Statement. Since client.am.Statement implements java.sql.Statement, we could remove those constants and let it inherit them instead. The only reason why these constants are defined in client.am.Statement, is to make the client compile on JDKs predating JDBC 3 (that is, Java 1.3 and earlier). Since we don't support those JDKs anymore, the constants can be removed now.
