Cayenne and Java 7

[Andrus Adamchik <an...@objectstyle.org>]

Noticed a Java 7 dev preview for OS X: http://jdk7.java.net/macportpreview/

So I downloaded and tried to do various things with it:

1. Starting M3 CayenneModeler - works.
2. Compiling Cayenne with Maven - doesn't work.

First the build hangs for about 30 seconds on an operation [1]. Adding -Djava.net.preferIPv4Stack=true doesn' help - it hangs on a similar IPv4 class. Looks like we are the victims on [2]. Anyways, the build proceeds, compiles a few modules, but then blows with a bunch of errors [3]... I guess those are related to JDBC 4.1 and we can extend our JDBC4 workaround - [4]
