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:
déc. 05, 2016 10:51:07 AM com.sun.faces.config.JavaClassScanningAnnotationScanner$ConstantPoolInfo containsAnnotation
GRAVE: Unknow type constant pool 0 at position 178
I tried different stuff to fix this warning but it always comes back.
Is this log a symptom of any issue ? Is it just a normal output? Is there a way to fix this?
I was presenting the same problem
Today I updated my pom.xml file to jsf version: 2.2.15 and that ERROR log was gone.
