Dear oxygen-user list:

I tried opening a file from a URL on a site that uses a self-signed certificate. <oXygen/> first asked whether I wanted to allow and trust the site, and when I told it that I did, <oXygen/> refused to load it, telling me that:

Cannot open the specified file.
There was a problem establishing the secure HTTPS connection. In case the server you are trying to connect to uses self-signed certificates, read the 'Troubleshooting HTTPS' section from the user manual.
Full error message: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I'm running XML Editor 21.1, build 2019120214, with the bundled Java, on MacOS Mojave. How do I communicate to <oXygen/> that it should trust this site? I tried adding an exception for the site to my Java configuration, which didn't help, and I then realized that that was probably because those exceptions are for my system Java, and <oXygen/> is using its own.

Thanks,

David
