Subject [jira] [Commented] (DERBY-6945) Re-package Derby as a collection of jigsaw modules
Date Mon, 01 Jan 2018 17:17:00 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16307500#comment-16307500
] 

Bryan Pendleton commented on DERBY-6945:
----------------------------------------

I like the idea of putting the external JDBC driver classes into derbytools.jar; it makes
sense to me to think of derbytools.jar as "the jar file where all the external classes that
you directly reference live". That is, things like sysinfo, ij, etc. are all just "entry points"
into the Derby functionality, which is also true of the client and embedded drivers.

But I think you went over that idea a bit too fast for me, at least your item (1) is confusing
to me.

If the JDBC Driver classes are in derbytools.jar, how does an application invoke a JDBC driver
using just derby.jar+derbyshared.jar or just derbyclient.jar+derbyshared.jar? Is one of those
jars automatically pulling derbytools.jar into the classpath somehow?

> Once we commit to building with Java 9 (see DERBY-6856), we should consider re-packaging
Derby as a set of jigsaw modules. This would result in a different set of release artifacts.
This might be a good opportunity to address the Tomcat artifactory issues raised by issue
DERBY-6944.
