ERROR .c.DefaultCoreExtensionScanner - Failed to convert to extension URL

Hi,
I am getting the below exception when restart glassfish 5. xwiki 10.4
Any help in this regard is much appreciated. Greeting from Chile.

You application server has some pretty weird URL in its classloader (which it’s not even able to load…) but in practice you can ignore this, it should not have any more effect than an annoying error log at startup

Would be nice if you could create an issue on Loading... and give as much details as possible to reproduce it (the application server, which version, which system, Java version, etc.).

Thanks @tmortagne,
I will do what you tell me…
