After migrating to new version of eclipse based application 2022-12 no longer able to get fields

While transitioning from an eclipse 2018 based application to eclipse 2022, various objects like #32770, ToolbarWindow32, sysTreeView32, sysTableView32, and others lose their visibility along with related properties, including Java properties. Additionally, the "fields" tab, along with all its values, is no longer accessible. Is there a way to restore the "fields" tab, as a considerable amount of code already relies on these fields for object identification?

This disparity becomes evident when using the object spy on the license agreement between both eclipse versions (2018 and 2022).
