I think there are licensing issues to be cleaned up in https://github.com/redhat-developer/omnisharp-theia-plugin/. Until we have those resolved, I'm blocking this PR.

Che 7.0.0 has been released. @svor what's the status of this PR?

@l0rd It will be merged once eclipse-che/che#14224 is fixed

License issues resolved

Tested on latest Che and found no significant issues.

• I still see Java LS "Classpath is incomplete" warning when loading petclinic che#13427 and need to refresh after restoring
• Completions on the sample project's Program.cs are kind of wonky, I can't get anything helpful there but it works for Startup.cs.
