I recently changed the URL I was monitoring from http to https. I got this error:

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target - sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I tried installing the certificate into cacert for the JDK the job is using but that didn't seem to help. This job does nothing but monitor a site.
