[rules-users] Null pointer exception when using global in rdrl 6.0.1.F

I have a class that I declared final, has a private constructor, has only
static members and methods.
Some of its members are static instance of classes.
In KIE-WBI added a global of that type with name X

When I try to make a call on X.foo(), I get a null pointer exception.  (note
that x.foo() calls y.foo(), where y is a static member of X.

I've read some posts that a global has to be static, am I stretching, what
it means for a global to be static?

I am guessing I need to write some java code that will create an instance of
X and inject into working memory?  I was hoping to be able to create this
object within either the drools or SY framework.

I have googled and be reading on this for quite a bit now, but I think I
have succeeded only in confusing myself.

Any help greatly appreciated.
