As I said, we are talking about different things. I am talking about running binary executables from old platforms and people making new binaries in the old way again, you seem to be talking about porting old source code to new platforms.
The new platforms may use the old languages, but the runtime libraries are not the same. The new platforms have different APIs and functionalities (no threads in TeaVM for instance).
To simplify my point. ActionScript is just a language. Adobe Flash was much more than that. Maybe companies really will find some compelling reason to start using ActionScript again... but Adobe Flash and it's SWFs will still be dead.
