> Currently a lot of code is duplicated between SetupJdkExecutable and SetupJdkLibrary. Furthermore, some functionality is still missing from SetupJdkExecutable that is present in SetupJdkLibrary. These functions also have not had their documentation properly updated as they have evolved. This PR will fix all of this.
