![]() ![]() Bypassing the issue was as easy as adding one more mapping to my /etc/hosts file for the 127.0.0.1 so it would map for the hostname. Apparently we were not the first ones to be hit by the issue and with the help of stackoverflow the solution was now at our fingertips. Thanks to the right keywords now in place, the solution was just one google query away. Due to yet unknown reasons this started influencing DNS lookups for localhost which now started to take 30+ seconds instead of milliseconds as before. The confusion increased when discovering the issue was not reproducing in our test matrix – throughout the dozens of machines in the matrix everything seemed to work well.Īnd then it struck – over the weekend, the good old Mac OS X in my laptop had upgraded itself to macOS Sierra. The Logback library stuck at () has been performing the lookups for localhost for ages.

First guess in hunt for the root cause of the issue was suspecting any of the recent changes in Agent. The problem was reproducible – attaching our Java Agent even to a tiny test application increased its startup from two seconds to 30 seconds. Until the moment I found myself waiting for our Java Agent startup for minutes instead of seconds. It had been tailwinds towards the release for weeks – everything was progressing nicely. ![]() The problem is that you’re not being routed to the correct download website when you click “More Info.”Īpple could have remedied this issue by programming the “More Info” button to direct you to the right fix.It was another Monday in the office, testing the next release of our user experience monitoring software. This isn’t a complicated issue to fix, but it is an indirect one. When you visit the download website to update Java, you find that the issue isn’t resolved! You’re still getting the same pop-up. Without a compatible Java command-line tool for these software, you’ll get this pop-up every time you turn on your Mac computer. Older software such as Adobe Photoshop and Illustrator requires legacy Java support. The reason you’re receiving this message is due to the removal of Java support in newer versions of OS X for security reasons. It says, “To use the java command-line tool, you need to install a JDK.” It asks you to click “More Info” and visit the JDK (Java Developer Kit) download website. After upgrading to a newer version of Mac OS X (Yosemite 10.10 and El Capitan 10.11) or macOS (Sierra 10.12 and High Sierra 10.13), you may end up getting an annoying new pop-up message whenever you start your computer.
