Why can't JRuby find it's

	public class RubyExtensionFinder extends ExtensionFinder {

	public RubyExtensionFinder() {
	ScriptingContainer jruby = new ScriptingContainer();

Why does Hudson only ask for certain extension points?

	@Extension
	public class MyExtensionFinder extends ExtensionFinder {

	public <T> Collection<ExtensionComponent<T>> find(Class<T> tClass, Hudson hudson) {
	System.out.printf("find(%s)\n", tClass.getName());
	return new ArrayList<ExtensionComponent<T>>();
	}

	A 5 vol% ethanol solution needs to be converted to wt% for the table in the
	CRC Handbook of Chemistry and Physics, 62nd Ed, pg D-207.
	The density of pure alcohol is 0.791 times that of water at 20 C.

	Basis 100 ml solution:
	alcohol = 5x0.791 = 3.955 grams
	water = 95x1.00 = 95.000
	Total = 98.955 g

	Wt% alcohol = 3.955/98.955 = 0.0400 -> 4.00 wt% alcohol.
