Flash is not necessarily installed on all machines, and when it is, it can be an old version that is blocked. All these differences can cause unexpected failures, depending on what you have installed. We have a number of tests that use Flash, but somehow pass even when it is not installed. They must be not very good tests, given that they don't detect this fatal condition! I'm going to clean up as much as I can, and to make WebKitTestRunner prevent attempts at using Flash in new tests.
Created attachment 250104 [details] patch for EWS Chances are that I got at least a few cases wrong... This also marks all remaining plugins/snapshotting tests as flaky, because they don't really test snapshotting at all, and just cause trouble. We would only be interested in crashes on these tests.

Comment on attachment 250108 [details] patch The patch fails to be applied (line endings?) But tests passed locally.
Comment on attachment 250108 [details] patch Can you remove the .swf files?
Committed <http://trac.webkit.org/r182428>. > Can you remove the .swf files? Not yet - they are still used in the 8 remaining tests that are skipped on WK2, but still run on WK1. We need to associate TestNetscapePlugin with an extension, and to make it load a resource to convert these.
