I thought that an inner class would reference all the members correctly, but it sees some of them as null when they are already initialized/assigned.

I tried these as work-arounds, and they worked fine:

• making members final,


• initializing members at declaration (outside the constructor).

My question is - what do I really have to do to ensure proper referencing to the outer class' members from inner classes' methods? I thought any member would be accessible from an inner class, which apparently isn't the case.
