java 21 jenkins passed However, will be making more additional changes, so will need reverify here after have a more final draft.

Removed unnecessary changes and confirmed compiling with Open XL upto latest wip error.
Cleanup of pragma packed changes. pragma packed and pragma reset is unsupported by Open XL, and pragma pack(push,1) and pragma pop(pop) is functionally identical and works with both XLC and Open XL on z/OS.
Pending to RE-verify Jenkins XLC build.
