We've had various reports that the JBS home page -- https://bugs.openjdk.org -- sometimes redirects to a login page. We link to the JBS home page on the main OpenJFX Wiki page at:

https://wiki.openjdk.org/spaces/OpenJFX/pages/8257538/Main

And from the CONTRIBUTING page at:

https://github.com/openjdk/jfx/blob/master/CONTRIBUTING.md

A workaround, and probably a better landing page anyway, is to link to the JDK project page on JBS rather than the home page:

https://bugs.openjdk.org/projects/JDK
