OpenAM Fresh Install Issue - HTTP Status 500 - AMSetupFilter.doFilter

Out of laziness, I reused an existing Tomcat instance that had OpenAM 12 installed and configured.

It's fast! 

Stop Tomcat; Remove OpenAM 12 war file and the exploded OpenAM 12 directory; Deploy OpenAM 11 was file; Start Tomcat. 

Bomb! As soon as Tomcat started, I encountered HTTP Status 500 error.

Took me a while to realize that I have not yet cleaned up the hidden OpenAM configuration.

[ec2@am0 ~]$ cd .openamcfg/
[ec2@am0 .openamcfg]$ ls -altr
total 16
-rw-rw-r--.  1 ec2:ec2   25 Mar  1 18:55 AMConfig_data_opt_am1200_webapps_auth_

This file pointed to a configuration directory where OpenAM 12 was previously installed. Now that OpenAM 11 was installed, the above AMSetupFilter.doFilter error appeared.

Stop Tomcat.

[ec2@am0 .openamcfg]$ rm -fr AMConfig_data_opt_am1200_webapps_auth_

Start Tomcat again.
