Hi Andrea,
I have found a build break when done using JDK7. The build breaks in Coverage
Experiment/NetCDF Grid Coverage Module.
This is caused by a subtle change in the definition of TreeMap#put(K key, V
value) in Java 7 when compared in Java 6. Look at the source code and follow
the code in Java 7 and a Comparable cast is made on keys. This is not done in
Java 6. This cast is the point at which the exception is thrown.

be cast to java.lang.Comparable

If I knew where the TreeSet in created and changed it to use a custom
comparator, then I believe that this would fix the breaking build. I haven't
tracked down the offending file (looking into this) but you may have a much
better idea.
