Over the past year this test started failing due to a timeout. It hangs when attempting to access the following image: https://openjdk.org/images/openjdk.png

Upon investigation I found that the image could not be retrieved at the time of failure even using wget.

After consulting with the ops team, confirmed that a server configuration change had been made around that time. As a result, repeated web requests especially those with non-browser user-agent headers may be blocked after some period.
