As announced in this message, the official jfx repository is moving from hg.openjdk.java.net/openjfx/jfx-dev/rt to github.com/openjdk/jfx.

This sandbox repository is being retired on 1-Oct-2019. You will need to migrate your WIP pull request to the openjdk/jfx repo if you want to continue working on it. Here are instructions for migrating your pull request. The updated CONTRIBUTING.md doc has additional information on how to proceed.

Once you have done this, it would be helpful to add a comment with a pointer to the new PR.

The new openjdk/jfx repo will be open for pull requests on Wednesday, 2-Oct-2019. I will send email to the openjfx-dev mailing list announcing this.
