Bug in parser? 2003-05-30 - By Jon Wilmoth
Ah. I thought
getClass().getResourceAsStream("test.xml") delegated

getClass().getClassLoader().getResourceAsStream("test.xml")
and it was the location of the file (i.e.
com/acme/app/text.xml) that specified the package to
look under not the invoking class.
