This is impressive! For folks who are worried about what this says about App Engine's security - historically the JVM level sandboxing was one part of an overall sandboxing story (not surprisingly, very similar to Chrome's setup) and my understanding, although haven't been on the team for a decade at this point, is that the JVM-level restrictions have been effectively replaced by a gVisor-based solution.
