Upon reflection I think this is very reasonable.  What I took from this is:

  * Bump the portlet's major version # (my interpretation)
  * Change all portlets we upgrade Spring on to build to Java 7,
    document accordingly

I like that and I can live with it.  Anyone running Java 6 is probably 
not updating their portlets, and they certainly have an easy upgrade 
path by just switching to Java 7 without changing any other part of 
their infrastructure.  Works for me (and is very desirable).
