Summary: DynamicJava can't handle certain variable names

Initial Comment:
This one is pretty amusing. It's almost certainly not our 
fault, but I guess we'll need either a workaround or a fix 
from the DynamicJava team: 

Define the following class in the Definitions Pane, and 
then save and compile:

"public class TestClass {}"

Now define the following variable in the Interactions Pane:

> testClass = new TestClass();

You will get the following error:

java.lang.NoClassDefFoundError: testClass (wrong 
name: TestClass)
  at java.lang.ClassLoader.defineClass0(Native Method)
  at java.lang.ClassLoader.defineClass
(ClassLoader.java:502)
  at java.security.SecureClassLoader.defineClass
(SecureClassLoader.java:123)
  at java.net.URLClassLoader.defineClass
(URLClassLoader.java:250)

(URLClassLoader.java:54)
  at java.net.URLClassLoader$1.run

  at java.security.AccessController.doPrivileged(Native 
Method)

  at java.lang.Class.forName0(Native Method)
  at java.lang.Class.forName(Class.java:217)

It looks like you'll get the same error for any variable that 
has the same name as its type (modulo capitalization), 
_provided that the type is user-defined_. Library classes 
such as String, StringBuffer, and Object won't trip the 
bug.

Strangely, there are no DynamicJava methods in the 
stack trace, but how could this be a bug in Java? 
Clearly, Java lets you perform variable assignments like 
the one above (in fact, I tripped over this error while 
pasting a working unit test into interactions).
