Dotnet Core 2.1 broke WriteToken() on Linux kernels (ObjectDisposedException)

See original GitHub issue

System.IdentityModel.Tokens.Jwt isn’t working anymore on our Linux environment when we try to generate a Jwt.

This problem is specifically in .NET Core 2.1 when calling new JwtSecurityTokenHandler().WriteToken(jwt)

An example of the bug can be found in this repo: https://github.com/AaronFixer/RsaMicrosoftIdentityJwtLinuxBug

Just run dotnet run from within a Linux distro (I did this on Ubuntu 16.04 and 17.10).

@brentschmaltz As you quite rightly pointed out, this issue isn’t actually a bug as disposed objects shouldn’t be available outside of their context.

On Windows however, the disposed object appears to still be available as the token is generated fine (run the code I originally submitted on Windows, and you’ll see the token is generated).

This isn’t correct behavior though. As it should throw the same error (ObjectDisposedException).

@AaronFixer can you explain to me what you mean about ‘still works on Windows OS’?
