Rick Hillegas commented on DERBY-3703:
--------------------------------------
Concerning the first patch: I can't prove that there won't be linkage errors on
some small platform vm. For modern vms which resolve references lazily, I think
there would not be a problem. However, a problem could occur on an old vm which
resolves references eagerly. See paragraph 2 in this section of the VM spec:
http://java.sun.com/docs/books/jvms/second_edition/html/Concepts.doc.html#22574
So Dan's objection stands.
I would like to clarify the proposals around creating dummy jar files for the
small platform api:
1) I think that if we go to the trouble of creating dummy sources to compile
against, then we should check those sources into Derby's codeline and build
them as part of the normal Derby build. I would propose putting them in the
following directories unless someone has a better idea:
java/build/jsr169/java/sql
java/build/jsr169/javax/sql
2) I just want to clarify that we are only talking about dummy sources for the
jsr169 api (java.sql and javax.sql) and not dummy sources for the entire CDC
api.

> It would be good to simplify the Derby build so that the whole product could
> be built out-of-the-box just from what's checked into the Derby repository.
> As a step toward this goal, it would be good to be able to build the jsr169
> support without having to download proprietary libraries.
