xstream is not in the latest master(removed here:75bedf9)

[grobmeier]

This is the published and downloaded version 2.1.0, I didn't build this from master. Is 2.1 published with this commit?

[rm5248]

no, that was done after 2.1 was released

[grobmeier]

The binary works using Java 11 and 15, but NOT with Java 8 or with Java 17.

I used Java 11 and it worked.
