Update the dependency on Guava (r06 -> 15.0)

[ebourg]

Hi,

Here is a patch upgrading the dependency on Guava. The latest release removed the MapMaker.makeComputingMap() method used by Stapler. The patch follows the migration guide published by the Guava team:

Thank you

Thank you for merging this change Kohsuke. Did you find an issue with Guava 15.0 that forced you to stick with 14.0?

No, it's just that I made a change independently to go up to 14.0, and I guess I was mostly a little worried about forcing a version that's too new. You've verified that people who want to use Stapler with Guava 15.0 can do so, and I guess 14.0 felt like a good middle ground for those who are still linking with earlier versions of Guava (directly or indirectly.) From what I can tell, 15.0 removes some of the APIs present in earlier versions, and it looked like a bigger compatibility risk for those people.

Do you feel strongly that Stapler should depend on Guava 15.0?

I have no strong opinion on the upgrade to 15.0. I just noticed the incompatibility when upgrading the Debian package for Guava. It broke stapler as well as sisu-guice, jython and closure-compiler. So I reported the issue to the projects to ensure they all work with the same version of Guava. As long as Stapler also works with 15.0 I'm fine.
