Doubt about ITypeHierarchy.getRootClasses() [message #259264]

Hello

in which situations does ITypeHierarchy.getRootClasses() return more
than one class?

Isn't an ITypeHierarchy always a tree?

Shouldn't there always exist a unique root, say "java.lang.Object" or
the last successfully resolved class?

Best regards,
Mário

Usually, there is indeed just a single root class (java.lang.Object).

But if you e.g. remove the JRE SystemLibrary from the build path of a
Java project and then compute the type hierarchy on a package, then
there may be multiple roots (which you can e.g. see in the Type
Hierarchy view).
