ProxyBuilder + no args method causes NullPointerException

[GoogleCodeExporter]

As originally reported by allurefx here:
http://code.google.com/p/mockito/issues/detail?id=308#c71

I'm getting an IllegalArgumentException when running verify() on methods with 
no args. Things are OK when there are args (from the 
InvocationHandlerAdapter.java source, looks like invoke(Object proxy, Method 
method, Object[] args) is getting a null for args). E.g.,

interface Whatever {
    void doStuff();
}

public void testWhatever() {
    final Whatever whateverMock = mock(Whatever.class);
    whateverMock.doStuff();
    verify(whateverMock).doStuff();
}

throws:

I couldn't reproduce this.

The error seems to be coming only if you run it as a JUnit test. E.g., add the 
attached test case to your project and run it as a JUnit test (not Android 
JUnit). You will need to add the libs/ jars to the class path. I tried, and I 
got the exception again.

The problem was that I had dexmaker library in the path even when using JUnit. 
Once I removed it, it ran fine.
