New Constructor calling a base

[VBCrazyCoder]

Why is this not legal?

Private x as String
Private y as String
 
Public Sub New(ByVal strParam As String)
x = strParam
End Sub
 
Public Sub New(ByVal strParam As String, ByVal strParam2 As String)
Try
MyClass.New(strParam)
y = strParam2
Catch e as exception
....
End Try

I can't put the MyClass.New call inside of the Try block? (It works fine outside).
