Question

I have a Java JSF2 web based application deployed on a Tomcat server, and since we moved to Java 8 / Tomcat 8 this error appears a lot in the tomcat output:

Answer 1

From my research it appears that this was a bug in JSF implementation and was fixed in JSF version 2.3.0-m02

Reported Bugs: http://github.com/javaserverfaces/mojarra/issues/3736 https://github.com/javaserverfaces/mojarra/issues/3780

Where to obtain fixed versions of the JSF implementation http://repo1.maven.org/maven2/javax/faces/javax.faces-api/2.2/ http://repo1.maven.org/maven2/org/glassfish/javax.faces/2.3.0-m02/

Or update maven POM dependency with (2.3.0-m02 or higher):

org.glassfish
javax.faces
2.3.0-m02
