/**
<p> This class finds transitive closure of dependencies from a given
root set of classes. If your project has lots of .class files and you
want to ship only those .class files which are used (transitively)
from a root set of classes, then you can use this utility. </p> <p>
How does it work?</p>
<p> We walk through all constant pool entries of a given class and
find all modified UTF-8 entries. Anything that looks like a class name is
considered as a class and we search for that class in the given
classpath. If we find a .class of that name, then we add that class to
list.</p>
<p> We could have used CONSTANT_ClassInfo type constants only. But
that will miss classes used through Class.forName or xyz.class
construct. But, if you refer to a class name in some other string we
would include it as dependency :(. But this is quite unlikely
anyway. To look for exact Class.forName argument(s) would involve
bytecode analysis. Also, we handle only simple reflection. If you
accept name of a class from externally (for eg properties file or
command line args for example, this utility will not be able to find
that dependency. In such cases, include those classes in the root set.
</p>
