Include package java.util.* in featureset
Include package java.util.* in featureset

This includes more classes than we really need, but it is a convenient
way to include a package that has nested classes directly in the package,
and also has nested packages. To be clear:

`java.util.ArrayList.ListItr` is an example of a nested class in package `java.util`
`java.util.stream` is an example of a nested package in `java.util`
