What about the Che server ? Don't we add certificates in the java truststore in the Che Java deployment as well ? Does it need the same fix ?

How do you manage the case where there are duplicate certificates (I assume we should be robust and ignore this error) ?
What about other errors when importing a certificate, Do we expect them to fail the start of the server ?

When adding a certificate into trust store we pass unique alias for it. So if user provides identical certificates - both will be added to trust store without any error.

What about other errors when importing a certificate, Do we expect them to fail the start of the server ?

Invalid certificates will not be imported, Keycloak and Che server will be started without invalid certificates

Thanks for the explanation.
