There's an important distinction: License. OpenJDK is GPL2.0, .NET runtime is MIT. They may be same in terms of openness, but not in freedom sense.

As a result, OpenJDK is much more sustainable in the long term, since it can't be closed down and crippled as easily.

While I am no enemy of MIT/BSD style licenses, the "freedoms" they provide to corporations are damaging to open source ecosystem in my eyes.

OpenJ9 looks like EPL licensed, and indeed interesting. It's worth a look.

I'm not writing Java with any considerable volume for some time (because, I didn't need that), hence I was just keeping that in my peripheral vision without paying much attention. However, I'm using Eclipse because it's a great IDE for my needs, and comes with OpenJ9 embedded.

Thanks for bringing this to my attention, will look deeper.
