**
** -#- -I- --Date-- -------------------------------Description--------------------------------
** 001 CA  20190526 First version, stubs taken by converting the skeleton using FWD.
** 002 IAS 20190527 Got rid of "abl" in names
** 003 CA  20191024 Added method support levels and updated the class support level.
** 004 MP  20200525 Added constructor and execute method.
** 005 CA  20210221 Fixed 'qualified', 'extent' and 'returns' annotations at the legacy
**                  signature.
**     ME  20210402 Added annotations, update support levels.
**     ME  20210929 Fix return value on createClientSocket, buildSocketConnectionParams.
** 006 CA  20231113 The 'execute' method must be annotated with LegacySignature Type.Execute, and also can be
**                  dropped if is a no-op.
