Dag H. Wanvik updated DERBY-5955:
---------------------------------

    Attachment: derby-5955-make-tests-run-03.diff

Attaching a new version of the tests patch, "derby-5955-make-tests-run-03.d=
iff", which makes the following change:

refactor JDBC#supportsNonJNDI to #supportsJNDI

It turned out there was few if any cases causing problems for the semantics=
 change, so the positive formulation is better.

Rerunning regressions.

> While waiting for a Java module system (aka project Jigsaw), it has been =
decided to define a few subsets of the Java SE Platform Specification, cf J=
EP 161 ( http://openjdk.java.net/jeps/161).
> A quote from the JEP: "More broadly, this feature is intended to enable t=
he migration of applications currently built on top of the Java ME Connecte=
d Device Configuration (CDC) to appropriate Profiles of the Java SE Platfor=
m, part of the long-term effort to converge CDC with Java SE."
> It would be good if we make Derby to run on such limited profiles. The cu=
rrent proposal places JDBC in Compact Profile 2 (cf. link above), while oth=
er libraries used by Derby, e.g. javax.naming (JNDI) are in Profile 3 (larg=
er).
> It would be good if Derby could run on the smallest posible platform, i.e=
. Profile 2, but that will probably involve some changes to make Derby grac=
efully limit functionality when some libraries are missing.
