Subject [jira] [Commented] (DERBY-5488) Add remaining JDBC 4.1 bits which did not appear in the Java 7 javadoc.
Date Fri, 04 Nov 2011 09:51:00 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13143876#comment-13143876

Knut Anders Hatlen commented on DERBY-5488:
-------------------------------------------

Thanks, the changes look good to me. I thought perhaps these changes might make ParameterMappingTest
work on CDC/FP now, so I enabled the test and ran it on phoneME and on Oracle Java ME Embedded
Client. It still failed, but now the failures were NullPointerExceptions. For example:

1) test_jdbc4_1_objectMappings(org.apache.derbyTesting.functionTests.tests.jdbcapi.ParameterMappingTest)java.sql.SQLException:
Java exception: ': java.lang.NullPointerException'.
	at org.apache.derby.impl.jdbc.SQLExceptionFactory.getSQLException(SQLExceptionFactory.java:45)

Do you see any reason why the call to setBigDecimal() should fail with a NullPointerException
here?

> In addition to the JDBC 4.1 bits which were visible in the Java 7 javadoc, a couple other
items appear in the JDBC 4.1 Maintenance Review spec. This spec has been published on the
JCP website at http://download.oracle.com/otndocs/jcp/jdbc-4_1-mrel-eval-spec/index.html.
I will attach a functional spec for the remaining bits.
