Description Alex Boyko

If Eclipse 4.18 is used as a dev environment for Eclipse plugin a common use case is to launch Eclipse runtime workbench.
If one attempts to navigate to http://localhost:8080 in the Eclipse embedded browser then the following error shows up:

Page load failed with error: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.

In other words it wants https.

It works fine in Eclipse 4.18 thus I'd expect it to work in the runtime workbench too

It has to do with Java 11...
If I modify runtime workbench launch config to launch with Java 11 (on 4.16) then it won't work either. As soon as I launch it with Java 8 it works fine

I have found that my servlet cannot be deployed / run / debugged from Eclipse 2021 06 or 09 but can be run ok from Eclipse 2021 03.

In both scenarios I'm using Apache Tomcat 9 with Java 11 (Zulu).

The version of Java does not make any difference to me - only the release of Eclipse.
