Summary: Class.forName() doesn't work in interactions pane

Initial Comment:
After defining the following class in the Definitions
pane and compiling, I have the interaction below.


class MyClass {
  static Class lookup() throws ClassNotFoundException {
    return Class.forName("MyClass");
  }
}


> MyClass.class
class MyClass
> MyClass.lookup()
class MyClass
> Class.forName("MyClass")
ClassNotFoundException: MyClass

It appears that something is wrong with the ClassLoader
used by Class.forName().


My Interactions classpath is as follows:

C:\Documents and
Settings\Dan\Desktop\drjava-beta-20041124.exe
C:\Program Files\Java\jdk1.5.0\lib\tools.jar
C:\cygwin\home\Dan\Misc [location of MyClass.java]

I've tested this on DrJava versions 20041124-2208 and
20040908-2125 under Windows XP Professional and Java 1.5.0.
