Rick Hillegas commented on DERBY-3984:
--------------------------------------
Hi Myrna,
Thanks for the review and for running those experiments.
I agree that it would be worthwhile to add a comment to the wiki, advising
committers that they should configure their build environment so that they get
compile-time checks for all of our platforms. The instructions for how to do
this are in the new BUILDING.html attached to DERBY-3985.
> Separate out the small number of build targets which really require JDK1.4
> features from the bulk of the targets which ought to compile cleanly against
> small device libraries

> It would be good to make jsr169 the default platform for most Derby build
> targets. This will allow the build to raise compile-time errors when a
> checkin violates the small-device contract. Only a small number of features
> (listed in DERBY-3966) really require JDK1.4. Something like the following
> may work:
> 1) Finish up DERBY-3966 so that java4compile.classpath defaults to an
> approximation of ${jdk14xmlSupport}: ${java15compile.classpath}
> 2) Make compile.classpath default to jsr169compile.classpath
> 3) Fortunately, jsr169compile.classpath itself already defaults to
> ${jsr169stubs}:${java14compile.classpath}
> 4) Change a (hopefully) small number of targets to use
> java14compile.classpath rather than compile.classpath
