Good idea about OpenJDK BTW... maybe I'll hack a little Maven module
based on OpenJDK with needed interfaces and post on on ObjectStyle.
Then we can have it as a "provided" (i.e. not bundled) dependency for
cayenne-jdk15-unpublished.
Let me float that on legal-discuss.

This will exclude 32-bit Mac owners from the dev process (I do have

how do we make it build on 1.5 (everything except for the 1.6
module of course). Here is one idea: a developer may extract the
new JDBC 4 interfaces from Java 1.6 (we can provide a little script
to do that), and build a small extension jar and drop it in the lib/
ext of JDK 1.5. That and also we will publish 1.6 snapshots for
downstream dependents (such as cayenne-server and cayenne-client).
Thoughts on that? Maybe there are better ideas (and I may need to
vet this little hack with Apache legal).
It may be easier to do this against OpenJDK rather than Java 6,
since the licensing is much simpler. But still, we bump into GPL
licensing of OpenJDK. The question: "is this code linked to ours"
such that it infects Cayenne code with the GPL license? Clearly
implementing an interface doesn't cause a problem (since we do that
for dozens of JRE interfaces) but can we write stubs for the
interface itself and bundle that without causing a problem? The
logical answer is that we are including no more intellectual
property than simply implementing the interface, but law is so
rarely that logical.
And of course the Java 6 problem for Mac users is not just 32 bit
machines, but also 64 bit PPC machines. I can't wait until Apple
just give up partially supporting Java and either Sun or the open
source community take it over to do it properly.
