We have mendix and an external java library working in Mendix 4 perfectly.
Trying to upgrade to mendix 5, using the same library and getting sun.util.calendar.ZoneInfo not found
Found this. After or during migration to 5 you may run in to errors about missing classes in packages sun or com.sun
Now I have built a testbed where functionality X works in a java container (Java 1.7.080), but inside the mendix container (Java 1.7.080) I get this issue.
My question is: Does Mendix 5 block the loading of sun and com.sun classes somehow, and is there a way to override this behavior?
