VMware and Red Hat are engaged in a legal battle over ownership of the Vert.x open source project. Similar to Node.js, Vert.x is an application development framework that runs on the Java Virtual Machine (JVM).
In the past, Vert.x development was led by former VMware employee Tim Fox. But when Fox went to work for rival Red Hat, VMware lawyers demanded that Fox return control of the project to the company.
For now, VMware has control of the Vert.x github project, the Vert.x google group, the domain vertx.io and the Vert.x blog. However, the Red Hat and VMware are currently engaged in negotiations about the future of the project. "It's important that we try to allay any fears and uncertainty that the community has about the vert.x project and state clearly that VMware and Red Hat are still very much in active discussion regarding how best to support the vert.x project going forwards," executives from both companies blogged in a joint post.
