== Why is this an issue?

Throwing such general exceptions as ``++Exception++``, ``++SystemException++``, ``++ApplicationException++``, ``++IndexOutOfRangeException++``, ``++NullReferenceException++``, ``++OutOfMemoryException++`` and ``++ExecutionEngineException++`` prevents calling methods from handling true, system-generated exceptions differently than application-generated errors. 

=== Noncompliant code example

[source,vbnet]
----
Public Sub DoSomething(obj As Object)
  If obj Is Nothing Then
    ' Noncompliant
    Throw New NullReferenceException("obj")
  End If
  ' ...
End Sub
----

=== Compliant solution

[source,vbnet]
----
Public Sub DoSomething(obj As Object)
  If obj Is Nothing Then
    Throw New ArgumentNullException("obj")
  End If
  ' ...
End Sub
