Proxy configuration issues with jvisualvm

Question

I have tried the jvisualvm.exe in my JDK (1.6.0_15-b03) to reload the plugin catalog, by following

Tools > Plugins > Updates > Reload Catalog

However; no matter what proxy configuration I try (I also tried to test it on another JVM 1.6 update 23) and does not seem to to work. I get the following errors irrespective of my proxy setup.

Unable to connect to the Java VisualVM Plugins Center because of sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Here is the error window that comes up [please see attached image]

Is this a known problem or some certification issue? I have never created a trust store on my machine, could this be a problem?

Answer 1

The VisualVM was migrated to Github so the plugins center is now Here

but to make it short what you need to do is
open VisualVM
open Tools -> Plugins -> Settings
on the right column ("Java VisualVM Plugins Center") click Edit
replace whatever you have there with : https://visualvm.github.io/uc/8u131/updates.xml.gz

Answer 2

In here you can download plugins manually: http://visualvm.java.net/pluginscenters.html
