Well, it says that the plugin requires Java 1.7, not that ImageJ requires
Java 1.7, although, to answer your question, ImageJ works with Java 1.7.

This is another issue: MacOSX' Java 1.7 support is unfortunately not as
stable as Java 1.6 support.

Therefore I would suggest to configure Netbeans to target Java 1.6.

Besides, it is always better to target *not* the latest and buggiest, but
the most prevalent, in this case, Java 1.6, *especially* if you want to
make your code available (which you should, as a scientist).

Ciao,
