[Stackoverflow] [Progress OpenEdge ABL] Expected exception is not caught in Unit Test

[Addie]

I have a Unit Test for a class "DbCommand" which in its constructor verifies if the first parameter receives the "?" value. If it does, it throws an ArgumentException.

CONSTRUCTOR PUBLIC DbCommand (dbConnection AS DbConnection,
                              cInstruction AS CHARACTER):

    IF (dbConnection = ?) THEN
        UNDO, THROW NEW ArgumentException("DbConnection must be valid":U) .

In the Unit Test I am assigning the first parameter with the "?" to verify that the exception is thrown. For that I added:

@Test (expect="System.ArgumentException").
METHOD PUBLIC VOID TestDbCommand ():

    DEFINE VARIABLE oDbCommand AS DbCommand NO-UNDO .

    oDbCommand = NEW DbCommand(?, "Delete") .

But the Unit test fails with the first line of the Failure trace being: "System.ArgumentException: DbConnection must be vaild"

Even though I am already expecting this? I have a few more places were I am using the exact exception and am able to get it caught in the @test header. But here it doesn't work.
