Understanding the com.sun.* APIs being (ab)used by the community

[Nicolai Parlog]

 Hi Stefan,

running jdeps as shown in Jonathans post (with "-v") "[p]rints all
class-level dependencies"[1]. This includes the ones which will not be
accessible in Java 9.

The bug you cite is based on a missing definition of some packages as
internal API, so running with -jdkinternals will not list them as
problematic.

 so long ... Nicolai
