Cause

An explicit protocol was not used.

Environment

Release : 12.x, 21.x,22.x

Component : Automic Workload Automation

Sub-Component: Automic Workload Interface (Tomcat 9)

Resolution

In Tomcat server.xml file change:

protocol="org.apache.coyote.http11.Http11Protocol"

To

protocol="org.apache.coyote.http11.Http11NioProtocol"

Additional Information

Note: In order to use an explicit protocol rather than rely on the auto-switching mechanism one of the below values may be used, choose as per your requirement

org.apache.coyote.http11.Http11NioProtocol - non blocking Java NIO connector
org.apache.coyote.http11.Http11Nio2Protocol - non blocking Java NIO2 connector
org.apache.coyote.http11.Http11AprProtocol - the APR/native connector.
