In a servlet, I'm trying to replicate this chunk of code from
ShibbolethV1SSOHandler.java:

String username =
support.getIdPConfig().getAuthHeaderName().equalsIgnoreCase("REMOTE_USER")
?
request.getRemoteUser() :
request.getHeader(support.getIdPConfig().getAuthHeaderName());

I don't have access to an IdPProtocolSupport object, so I tried the following:

IdPConfig idpConfig =
new IdPConfig((Element)
IdPConfigLoader.getIdPConfig(getServletContext()));
String authHeaderName = idpConfig.getAuthHeaderName();
String username =
authHeaderName.equalsIgnoreCase("REMOTE_USER") ?
request.getRemoteUser() : request.getHeader(authHeaderName);

But when I request the servlet, I get this runtime error:

java.lang.ClassCastException:

Any suggestions or ideas?
