Hi
Kindly raise a PR for integrating into Apache NetBeans GitHub https://github.com/apache/netbeans

This plugin is orginally based on code from the "I18N Checker" plugin from Jan Lahoda. The original sourcecode can be found at http://hg.netbeans.org/main/contrib/file/tip/editor.hints.i18n

License is CDDL-GPL-2-CP - http://www.netbeans.org/cddl-gplv2.html

If @jlahoda relicenses the original code to Apache 2.0, I could relicense this plugin too. Then it would be compatible to Apache NetBeans.
