22051	SSL Exception makes JOSM unusable	josm@…	team	"Starting JOSM, I get loads of Exception tracebacks with ""PKIX path building failed"" and SSL validation errors. First, no MOTD but a popup with a long line basically mirroring the tracebacks (""Error initializing test ApiCapabilitiesTest: …""), and the offer to change my proxy settings. Attempting to download data to edit results in ""Failed to upload data to or download data from $URL due to a problem with transferring data. Details: $traceback"" ($URL and $traceback contain text)

All SSL- and specifically java/SSL-related ubuntu packages (ca-certificates, ca-certificates-java, ssl-cert) seem to be installed correctly.
