Re: r1636063
I think it is wrong to change ScopedAttributeELResolver to implement this fix.
Thus I am REOPENING this.
The ScopedAttributeELResolver is defined by JSP specification (see JSP.2.9
Resolution of Variables and their Properties) and by its javadoc [1]. Those
describe exactly what it does.
It should not resolve imported classes - those are EL implementation
responsibility, not JSP one.
The EL3.0 specification says in several places that ELResolver is responsible
for resolving "model objects". An imported class is not a model object.
In EL3.0 specification there is chapter 1.5 Resolution of Model Objects and
their Properties or Methods.

1.5.3 Evaluating objects with properties
The steps for evaluating an expression with [] or . operators (property
reference and method call) are described in Section 1.6, “Operators [] and .”.
However, the syntax for . operator is also used to reference a static field, or
to invoke a static method. Therefore if the expression with a . operator is not
resolved by the ELResolvers, and if the identifier for the base object is the
name of an imported class, the expression becomes a reference to a static
field, or an invocation of a static method, of the imported class.

Note "Therefore if the expression with a . operator is not resolved by the
ELResolvers" phrase. It is not ELResolver's responsibility to perform a
resolution here.
