**
** -#- -I- --Date-- ---------------------------------------Description----------------------------------------
** 001 CA  20190526 First version, stubs taken by converting the skeleton using FWD.
** 002 CA  20191024 Added method support levels and updated the class support level.
** 003 ME  20200415 Instantiate logger as needed to avoid invalid handle errors, fix error handling/reporting.
**         20201208 Fix entity get/set signature, implement log methods.
**         20210204 Allocate memory when reading from file input stream.
** 004 CA  20210221 Fixed 'qualified', 'extent' and 'returns' annotations at the legacy signature.
** 005 ME  20210310 Use initInput in setter methods to avoid issue with 'invalid' object when value is 
**                  directly returned by a method.
**     VVT 20210917 Javadoc fixed, missing @Override annotations added.
**     ME  20210929 Fix function block for some methods.
** 006 CA  20230817 Removed ObjectOps.register, as this registration is handled by runtime.
** 007 CA  20231113 The 'execute' method must be annotated with LegacySignature Type.Execute, and also can be
**                  dropped if is a no-op.
