#142 package/variable conflict not resolved correctly

The following bug appears to have been introduced in
Beanshell 2.0b1:

In my tests for Beanshell I have the following test. I
define a class bsh.BSHArrayInitializerTest. In this I have
three inner classes, A, B, and C where A extends B and
C extends B. I interpret the following code:

public void testArrayInitializer() throws EvalError {
Interpreter.DEBUG = true;
Interpreter i = new Interpreter();
i.eval("new bsh.BSHArrayInitializerTest.B[] {new
bsh.BSHArrayInitializerTest.A(), new
bsh.BSHArrayInitializerTest.C()};");
}

This should pass without exception, and did in 1.2b1
(haven't tried in 1.3).

In the current CVS (2.0b1) it gives a UtilEvalError of
undefined variable or classname while evaluating
bsh.BSHArrayInitializerTest.A.

With debugging turned on the following stack trace is
printed. (v long). It looks like package vs variable name
resolution isn't happening properly.
