The CDDL license template has format

   ${licenseFirst}
   ...
   ...
   ${licenselast}   

that is, it requires that FreeMarker variables "licenseFirst" and "licenseLast" are defined.

I believe this format was made with an idea of block comments (in Java, HTML, JSP, etc.) in mind. However, not all
languages and file formats support block comments - for example, .properties files do not support block comments. So
what value should be set to "licenseFirst" and "licenseLast"? Empty string! But that leads to empty lines in place of
${licenseFirst} and ${licenseLast}. I suggest that the license templates are changed such that "licenseFirst" and
"licenseLast" are not required:

   <#if licenseFirst??>
   ${licenseFirst}
   </#if>
   ...
   ...
   <#if licenseLast??>
   ${licenseLast}
   </#if>

This should be made into NetBeans 6.0 (until people develop their own license files based on the default ones).
