Cachefu classes don't compile with Java 1.5

[shawnlauzon]

The existing POM file depends on 1.5. However, the cachefu classes use the @Override functionality on interface implementations, which are only allowed in 1.6.

This can be fixed either by depending on Java 1.6 or removing the @Override annotations. Personally I like using @Override on interface implementations, but I don't know if there's a reason it's built for 1.5.

yeah good point, source compatibility should be set to 1.6.
