Jenkins is being a pain

[Cantor, Scott]

I think it's mostly working now, but it's still failing a test of the
SVNResource class in java-shib-common.

I knew the Java 7 change would break it, but something also seemed to
break it running maven for the multi- builds. I had to manually pull down
the drop down in each project and select the Maven install to use, even
though there's only one.

Anyway, I removed the Java 6 JDKs from the V3 projects.

The other thing was that one of the decryption tests in V3 started
failing, and the error mentioned the RSA encryption size. I didn't think
RSA was one of the limited algorithms, but I tried to fix it by adding the
full-strength policy jars into the JDK install.

I also noticed something weird about the test failing, because the stack
trace seemed to be saying that Bouncy Castle was the JCE used.

So couple questions:

- do the V3 tests currently actually require the full-strength JCE policy
jars?

- does the inclusion of Bouncy Castle in the classpath make it the JCE at
this point? And do we want that? (I think we don't.)
