Oracle Announces Java SE 9 and Java EE 8 (oracle.com)
rastos1 writes: Oracle has announced the general availability of Java SE 9 (JDK 9), Java Platform Enterprise Edition 8 (Java EE 8) and the Java EE 8 Software Development Kit (SDK). JDK 9 is a production-ready implementation of the Java SE 9 Platform Specification, which was recently approved together with Java EE 8 in the Java Community Process (JCP). Java SE 9 provides more than 150 new features, including a new module system and improvements that bring more scalability, improved security, better performance management and easier development to the world's most popular programming platform.
.NET Core, which is pretty much .NET remade to be cross-platform, is also for Mac OS/Linux too now. And I won't be surprised if platform support increases in the future though I don't think they've announced any plans for that yet.
