[rules-users] Eval0Invoker : java.lang.NullPointerException

[Michael Anstis]

Yes, you should not be using globals to hold information you want to reason
over.

You can try re-writing the combined check to something like this:-

rule "Customer and Service Context null check rule"
no-loop true
salience 1000
       when
               not ( Customer() and ServiceContext() )
       then
               throw new MissingEntryFault("Customer and ServiceContext are
both required");
end
