Hi there,
I like to do some early adoption tests with software using the new module
system. Now we got an unknown amount of split packages in our system, the we
will need to fix in order to migrate our codebase.
I could imagine, that there are other potential users of the JDK, that have the
same problem to solve. So I think it would be a good thing to have some
detection within the jdeps tool or even have some kind of an API that could be
used otherwise (as of in a IDE).
Now I wanted to know what you think about this? I would also be prepared to do
some work in that area.
A tool to detect split packages and some other characteristics to aid migration
to modules would be useful. I tend to think that belongs to a different tool
that can build other additional analysis in it.
For split packages, it’d be useful to differentiate if the split package
contains overlapping classes vs partitioned classes. For partitioned classes,
renaming the package would likely be one solution if it doesn’t need to live in
a specific namespace. For overlapping classes, one possibility is that the
class path contains multiple copies of the same version or different version or
patched version of a library, or redistribution.

I think it would be good to have a "class path analysis tool" that can
take a classpath, and report which packages are found in which entries
on the classpath, and whether any packages are split between multiple
entries, or whether any packages are completely by hidden by earlier
entries.
