Please provide any additional information below. Attach a screenshot if possible.

Could not reproduce it but it looks dangerous, so I thought I better report it. It happened after an svn update to r14507 and testing the changes for r14508. This report was created with r14508 after

ant clean dist.

so ignore the version number.

On Windows we need to trick the OS to make it download trusted certificates on its own. We do this for a handful of certificates (mostly governmental) listed in CertificateAmendment. Once Windows has downloaded and installed the certificate, we don't need to request it again. That's why you can't reproduce it: it's likely the second try succeeded and it won't happen again unless you manually uninstall the Taiwan certificate.

fix #17069 - reduce severity/verbosity of errors when fetching certificates on Windows
