原因
There is an NTLM based proxy in place between Confluence and the internet
回避策
The Cntlm Authentication Proxy can be used to forward requests coming from Confluence through the proxy
ソリューション
As NTLM proxies are not supported for Confluence, a solution within the product is not guaranteed. See the bug report, When using NTLM proxy, NoClassDefFoundError for class /ietf/jgss/GSSException, for more details.
