"Interface implemented twice" 2.0 compiler bug?

Given this file (Stuff.js):

public class MyClass
{
public static interface MyInterface
{
public void DoThingA();
}

public class MyOtherClass
{
public static interface MyInterface
{
public void DoThingB();
}
public class MyImplementer implements MyClass.MyInterface,
MyOtherClass.MyInterface
{
public void DoThingA() {};
public void DoThingB() {};

public static void main(String[] args) {}

Doesn't compile in 2.0 J#:

C:\TEMP\vjs>vjc Stuff.js
Microsoft Visual J# (R) Compiler version 8.0.50727.42
for Microsoft (R) .NET Framework version 2.0.50727
Copyright (C) Microsoft Corp 2000-2002. All rights reserved.

Stuff.js(17,8): error VJS1159: Interface 'MyInterface' is implemented
twice

C:\TEMP\vjs>

But compiles fine in prior version:

C:\TEMP\vjs>\WINDOWS\Microsoft.NET\Framework\v1.1.4322\vjc.exe Stuff.js
Microsoft (R) Visual J# .NET Compiler version 7.10.3077.0
for Microsoft (R) .NET Framework version 1.1.4322

C:\TEMP\vjs>

Is this a compiler bug Seems to me it should compile. (Same results
whether the interfaces are declared static or not).
