The setting 'Tools | Options | Java Code | Formatting | Category 'Blank 
Lines' | After Class Header' controls the number of newlines inserted. 
By default, it is set to 1, which is why the extra line is added. It can 
be set to '0' to avoid the extra line. 

The setting affects both the main class header and anonymous class 
headers; if you feel they should be separately  controllable, you may 
want to file a request-for-enhancement at 
http://www.netbeans.org/community/issues.html
