APAR status

When performing a login into Admin Center, access.log will
show a request being made from the Liberty server to the
reverse proxy server.  This could cause Admin Center
preferences (like Bi-di) to not load.

****************************************************************
When performing a login into the Admin Center through a reverse
proxy, the access.log will show a request being made from the
Liberty server to the reverse proxy server.  If the Liberty
server does not trust the reverse proxy because the reverse
proxy server lacks the Liberty server's SSL/TLS certificate,
Admin Center preferences (like Bi-di) will not load and the
following error will be seen in the logs:
Error code FDC1015I:
Exception: unable to find valid certification path to requested
target com.ibm.ws.ssl.core.WSX509TrustManager
checkServerTrusted

Problem conclusion

The Liberty server now correctly calls itself instead of
attempting to route the call through the proxy server.

The fix for this APAR is currently targeted for inclusion in fix
pack 18.0.0.2.  Please refer to the Recommended Updates page for
delivery information:
http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980

Temporary fix

Enable two-way communication between the Liberty and proxy
server by exchanging SSL/TLS certificates; this will allow the
call to from Liberty to the proxy server to be routed back to
and handled by the Liberty server.
