Build of openoffice-3 causes openjdk6-b27-4 build (instead of openjdk7), and fails there

[Yuri]

When I try to build openoffice-3 it proceeds to openjdk6 dependency and 
fails:
---log---

On another machine I see that openoffice-3 depends on openjdk7.

This isn't right that the older version openjdk6 is the default for build.
