There is no direct "root type": they are probably most directly
reachable via the java.lang.Class instances when iterating over the
ClassLoaderDataGraph; search for ClassLoaderDataGraph::oops_do() and
ClassLoaderDataGraph::always_strong_oops_do(). I.e. the _class_loader
member of the ClassLoaderData class.

If your question is during which root scanning task the CLDG will be
iterated, it's the SH_PS_SystemDictionary_oops_do task. See also
SharedHeap::process_strong_roots().

The code that finds the static members within a java.lang.Class instance
is in instanceMirrorKlass.?pp.

Hth,
