APAR status
Closed as program error.
Error description
If query value of a filter condition returns null, the OIDC TAI might emit a java.lang.NullPointerException and not intercept the request. For instance, if the filter is Referer%=acme.us.com and there is no Referer for the request, an NPE occurs. This issue does not occur when general HTTP headers do not exist. For instance, if the Authroization header is not on the request, and the filter is Authroization%=Bearer, an NPE does not occur.
