the htmlunit installation have on system includes both htmlunit-2.15.jar (let's call "main" jar) , htmlunit-core-js-2.15.jar (let's call "corejs" jar). looking inside 2 jars, can see main jar has com.gargoylesoftware.htmlunit.javascript.regexp.*, while corejs jar has net.sourceforge.htmlunit.corejs.javascript.regexp.*:

normally, once installed, these 2 jars live in same directory. so, if case you, easier use wildcard syntax in $classpath both of them in 1 shot.
