Eclipse Che extension doesn't get loaded using Docker for Mac

We did set CHE_ASSEMBLY env var correctly pointing to our extension che assembly, but no matter how we tried, it just did not show up in the eclipse che IDE. It did work if we switched to mac virtualbox docker.

Reproduction Steps:

1. build a helloworld eclipse che extension following these steps: https://eclipse-che.readme.io/docs/helloworld-extension. Or you can clone my examples: https://github.com/guiguan/che, and https://github.com/guiguan/che-helloworld-sample. Remember to mvn clean install che-helloworld-sample first then che
2. export CHE_ASSEMBLY={path_to_che_assembly_assembly-main/target/eclipse-che-{che_version}/eclipse-che-{che_version}}
3. che start
4. visit localhost:8080, and create a workspace

Expected behavior:

“Hello World” notification should be displayed in the list of events

Observed behavior:

No “Hello World” printed

Che version: tried nightly, latest, 5.0.0-M7, and none of them worked on Docker for Mac OS and version: macOS 10.12.1 Docker version: 1.12.3 Che install: Docker container

Additional information:

• Problem started happening recently, didn’t happen in an older version of Che: No
• Problem can be reliably reproduced, doesn’t happen randomly: Yes

This checkbox works for all Chrome browser tabs and after restart browser too. If you don’t want use it, you should periodically(when you have a problem) clean up cash by application domain: for Google Chrome open development tools by F12 , move cursor to page reload button (with circle arrow above browser page) click and hold this button until appear drop-down menu, select in the menu “Empty Cache and Hard Reload”. See more: http://superuser.com/questions/278948/clear-cache-for-specific-domain-name-in-chrome Problems with cash is depends on tools which are you using for development. Sometimes all works fine, sometimes you have a problem with cash.
