"Unknow type constant pool at position X" in tomcat logs since java 8

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):

<groupId>org.glassfish</groupId>
<artifactId>javax.faces</artifactId>
<version>2.3.0-m02</version>

I had the same same problem. I solved after updating my pom.xml file to 2.2.11.

<groupId>com.sun.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.2.11</version>

<artifactId>jsf-impl</artifactId>
<version>2.2.11</version>

The postConstruct wasn't been execute in some ManagedBean, without any error.


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.
