Pavle please look at this. The problem is that both enums and
annotations have implicit superclass (i.e. Enum and Annotation are not
in the identifier index for files containing enums and annotations so
the subclasses are not found).
I see two ways how to fix this:
1) call refAllOfClass() on JavaEnumClass/AnnotationTypeClass to get
all subclasses of java.lang.Enum/java.lang.annotation.Annotation or,
2) automatically add hashcode of "Enum"/"Annotation" identifier to
identifier array of every resource containing definition of an enum or
annotation (in JavaUpdater and ClassUpdater)

Fixed.

Find all subtypes of java.lang.anotation.Annotation doesn't work. It finds
nothing although the project contains user defined annotations.
If it's desired behaviour feel free to close this issus again.

It is regression caused by performance optimization. I work on fix.
