The extension is registered in the extension manager
it has populated serverThumbprint in the vim.ExtensionManager.extensionList[my-extension].server (see attachment)
but when my java code doing a rest requests to the server it always gets an exeption:
com.sun.xml.internal.ws.client.ClientTransportException: HTTP transport error: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
