Questions about jigsaw API

I'm adapting sigtest tool ( sigtest.java.net ) to jigsaw and have some
questions about jigsaw API:
1) I need to read class bytes for any particular class and all its
dependencies. In other words for module com.acme.mod at 3.1 I have to
analyze com.acme.mod at 3.1's classes, their superclasses from other
com.acme.* modules recursively and their platform superclasses including
java.lang.Object. Maybe I missed something but I can't find easy way to
do it. So I resolve all dependencies manually. This is my the main
question. I very appreciate any recommendations.
2) org.openjdk.jigsaw.Library byte readClass(ModuleId mid,
java.lang.String className) according to the javadoc "reads the class
bytes of the given class within the given module, in this library or in
a parent library." But actually it doesn't read a parent library. Please
correct the description or, better, add this functionality.
3) I expected that
"java.lang.Object") returns Object's bytes. It returns null because
Platform.bootModule() is "jdk.base at 8-ea" instead of "jdk.boot at 8-ea".
4) I noticed that public org.openjdk.jigsaw.LoaderPool has no public
constructors. If there is no reasons for such design it's better to do
it not public ( like LibraryPool ) or make them all public.
Thanks in advance,
