With the recent update of Mac OS 10.13 (High Sierra), “Flash Builder stopped working”
error is encountered when you click Project-> “Export Release Build”.

If you are facing this issue follow the steps below:

  1. Download the attached zip ( which contains 2 jar files.
  2. Copy the 2 jar files and paste them at the location: “/Applications/Adobe Flash Builder 4.7/eclipse/plugins/”.
  3. Restart Flash Builder.

As a side note, if you build on the command-line you don’t really have this problem ;).
