Subject [jira] [Commented] (DERBY-6213) Deprecate support for Java 5 and CDC
Date Tue, 14 May 2013 18:39:16 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13657343#comment-13657343

Knut Anders Hatlen commented on DERBY-6213:

If I build with JDK 7 and don't have j16lib set, java16compile.classpath is set to the exact
same value as java17compile.classpath. I had expected that the JDBC 4.0 stubs would be prepended
to java16compile.classpath in that case.

The build failure happens because ClientDataSource & co are compiled against java16compile.classpath,
which is actually java7compile.classpath, and therefore expect the JDBC 4.0 DataSources to
implement the JDBC 4.1 interface.

It's probably a good idea to push the JDBC 4.1 methods into the base DataSource classes now
anyway, so I think I'll do that. Even so, it looks as if there may be a bug in the property

> The developer community has approved the proposal to sunset support for Java 5 and CDC:
> This issue tracks a number of tasks needed to implement this proposal:
> I) Remove build support for Java 5 and CDC.
> II) Purge user doc references to Java 5, CDC, and the JDBC 4 DataSources.
> III) Remove the JDBC 4 version of the public api from the published javadoc. The recently
introduced CP2 DataSources would need to migrate to the JDBC 3 version of the published javadoc.
The JDBC 4 versions of the DataSources would still exist, but they would be vacuous extensions
of their JDBC 3 counterparts.
> IV) On the wiki, document our expectation that maintenance releases will support the
same platforms as the original feature release cut from their branch.
> V) Decide what to do with the SimpleMobileApp. Probably we want to just remove this demo
since its purpose is to show how to run Derby on the deprecated CDC platform.
