Subject [jira] Issue Comment Edited: (DERBY-3984) 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

----------------------------------------------------------------------

This patch is based on the first attempt at check-in for DERBY-3988...Could you please update
it ?
The patch didn't apply cleanly to the current trunk (although it only had a problem with trunk/build.xml...and
I was able to change that quite easily manually, or I could apply to revision 727106, but
 I'd like us to be on the same level).

> 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
