Netbeans why does some text appear bold in roboticket?

i downloaded the xml file for roboticket from http://www.eclipsecolorthemes.org/, then i went to the http://svenspruijt.nl/themebuilder/ imported this xml file and saved it as a zip. then i imported this zip file in my eclipse. But some text appears to be lighter than usual (like function calls). so it is the same theme but why different appearances in different IDEs? I even checked in preferences fonts and colors tab -> syntax tab -> in language list java, went off each item and made sure it doesn't have anything bold in it
