When we try to display the list of APIs in the CA API Developer Portal then nothing is displayed. We get an error message in the Catalina.out file. This error message seems to be related to an API we had referenced earlier but removed from the list of APIs (removing "Set as Portal Managed" from its policy. 

Symptoms: Unable to get the list of API in CA API Developer Portal

Catalina.out file in portal shows following stack trace
