Sample project reproducing the problem

When I try to deploy attached project to device, packaging fails with error:
"D:\misc\M4ABugRepro\M4ABugRepro\M4ABugRepro.csproj" (SignAndroidPackage target) (1) ->
(_CompileJava target) -> 
  obj\Release\android\src\m4abugrepro\TestFilter.java(28,9): error :  TestFilter(m4abugrepro.AbstractAdapter_1) is already defined in m4abugrepro.TestFilter [D:\misc\M4ABugRepro\M4ABugRepro\M4ABugRepro.csproj]
obj\Release\android\src\m4abugrepro\TestFilter.java(28,9): error : 	public TestFilter (m4abugrepro.AbstractAdapter_1 p0) [D:\misc\M4ABugRepro\M4ABugRepro\M4ABugRepro.csproj]
obj\Release\android\src\m4abugrepro\TestFilter.java(28,9): error :  [D:\misc\M4ABugRepro\M4ABugRepro\M4ABugRepro.csproj]

Bug is reproducable always on Mono for Android 4.0.1 running on Windows and Visual Studio 2010. It works with m4A 4.0.

Steps to reproduce:
1. Open attached project.
2. Try to deploy to the device.
Comment 1 Jonathan Pryor 2011-12-22 10:21:44 UTC
The problem is M4ABugRepro.TestFIlter. The ACW contains:

	public TestFilter (m4abugrepro.AbstractAdapter_1 p0) {...}

	public TestFilter (m4abugrepro.AbstractAdapter_1 p0) {...}


It looks like the logic of "generate all base constructors, then generate current constructors" doesn't check to see if the current ctor was already generated in the base case.

Fixed in commit a3d0015f.
