Groovy Base script redundancy

According to Groovy documentation the following construction:

CompilerConfiguration conf = new CompilerConfiguration();
conf.setScriptBaseClass(scriptBaseClass);
groovyClassLoader = new GroovyClassLoader(GroovyUtil.class.getClassLoader(), conf);

is equivalent to running the a script containing the @BaseScript annotation.

In org.apache.ofbiz.base.util.GroovyUtil instead of choosing one solution, we are doing both.
