Wrong Hint suggestion with Dummy Variable prefixes

[Roeland]

Consider the following method:

procedure Test (p_Test_Id in Number default null) is
  Dummy_Test_Id Number := p_Test_Id;
begin
  Null;
end Test;

This gives the following error message:

Compilation errors for PACKAGE BODY TEST

Error: Hint: Variable 'Dummy_Test_Id' is declared but never used in 'Test'
Line: 4
Text: Dummy_Test_Id Number := p_Test_Id;

If I rewrite the method it works correctly:

procedure Test (p_Test_Id in Number default null) is
  Dummy_Test_Id Number;
begin
  Dummy_Test_Id := p_Test_Id;
  Null;
end Test;

In the "Dummy Variable prefixes" preference I have the value "Dummy"

This is correct. The dummy prefix applies to unused value assignments like your last example. It does not apply to unused declarations.
