JLS, 2nd Ed., 15.9.1 reads:

"If a class instance creation expression does not declare an anonymous class,
then:
     . . .

     Otherwise, the class instance creation expression is a qualified class
     instance creation expression. It is a compile-time error if Identifier is
     not the simple name (6.2) of an accessible (6.6) non-abstract inner
     class (8.1.2) T that is a member of the compile-time type of the Primary.
     It is also a compile-time error if Identifier is ambiguous (8.5). The
     class being instantiated is the class denoted by Identifier.

The type of the class instance creation expression is the class type being
instantiated."

Java compiler jdk1.4.0beta-b47 reports error message while compiles program
with the same name of declared top-level or inner class and first component
of declared package.
