This is a good move. With Java under Oracle's control, Microsoft has a lot to gain by embracing open source licensing.

That makes me believe there is no protection against contributor patents in the Apache 2.0 license...

At least they won't sue you if you use it under Windows.

Does the Apache license include patent licensing? Java is open source too.

3. Grant of Patent License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by such Contributor that are necessarily infringed by their Contribution(s) alone or by combination of their Contribution(s) with the Work to which such Contribution(s) was submitted. If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed.

Does it mean anything in particular that they chose the Apache 2.0 license? Their previously public plans were to use MS-Pl.

Just got through installing Ubuntu.

I expect to see some really good software come out of this. I think Microsoft bought a lot of goodwill with the community with this move.

Java is Oracle stack, C# is MS stack, objective-C is Apple stack.

Is there an opportunity for an open language with similar VM ease-of-use/performance tradeoffs - or is hardware now fast enough for the ease/speed of dynamic languages to fill that gap (Python, Ruby, Javascript, ...)?
