EmbeddedConnectionPoolDataSource does not implement java.sql.Wrapper but
reports JDBC 4 compliance when run with JDK 6
-----------------------------------------------------------------------------------------------------------------------
Key: DERBY-2582
URL: https://issues.apache.org/jira/browse/DERBY-2582
Project: Derby
Issue Type: Sub-task
Components: JDBC
Affects Versions: 10.2.2.1
Environment: JDK 6
Reporter: Stan Bradbury
Software that checks the value returned by the dataseMetadata method
getJDBCMajorVersion for JDBC compliance level and, based on the value, takes
different paths in the code will fail unexpectedly accessing java.sql.Wrapper
when loading EmbeddedConnectionPoolDataSource in a JDK 6 environment.
EmbeddedConnectionPoolDataSource reports a compliance level of 4 when loaded in
a JDK 6 environment. It returns JDBC 4 objects but the Datasource itself does
NOT satify the JDBC 4.0 interface Wrapper and so, not being fully compliant,
should not report JDBC 4 compliance.
JSR 221 does not detail the behavior of the dataseMetadata method
getJDBCMajorVersion but the description in Section 6.3, JDBC 4.0 API
Compliance, states: "A driver that is compliant with the JDBC 4.0 specification
must .. Fully implement .. java.sql.Wrapper". As Dan stated in his comment on
DERBY-2488, (http://issues.apache.org/jira/browse/DERBY-2488#action_12485033)
EmbeddedConnectionPoolDataSource does not implement Wrapper.
