says:
"IllegalAccessException - if the class or its nullary constructor is not
accessible."
Therefore I would guess that
(1) your class doesn't not have a no-arguments constructor
or (2) your class does have that constructor, but it is not public

No I do have a constructor in the class, and it is public. But on the other
have, in the extension I import packages defined in the main runtime. Could
it be that?

"import" only affects compile time name resolution.

I would expect a problem with name resolution to show up as an exception
on the Class.forName call. However, there could be an accessible class
with the right name, but without an accessible no-args constructor.

Just in case, if you are not already doing so, try passing a fully
qualified name to Class.forName.
