If plugin list download fails there is no message to the user about it

[pendluuum]

If plugin list download fails there is no message to the user about it. A special case follows but I suspect this happens with all download errors:

If the user changes the plugin list URL from http to https (https://josm.openstreetmap.de/plugin ...) list download fails with this error in the console:

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path bu
ilding failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find va
lid certification path to requested target

but no error is thrown in the GUI.

Impact: If a plugin list was downloaded before the user may not notice at all that the list update failed which means that he will never get newer plugin versions.

Expected: At an error should be shown in the GUI.

As suspected: There is also no error message in the GUI if there is some other download error. Another special case: "java.net.UnknownHostException: josmd.openstreetmap.de" because of a wrong address/typo.

I do not understand why this bug was re-classified as "enhancement". It is an error in JOSM if no error is shown when the action triggered by the user does not do what it is supposed to do. Or does JOSM follow the paradigma "no news is bad news" (in contrast to "no news is good news")? ;-) Or is the user of JOSM supposed to only start JOSM from a text console window to see such unhandled exceptions if something goes wrong?

The error appears on the standard output. Giving a user friendly one is an enhancement.
