JSF 2.1.x - Wildfly 10 Caused by: java.lang.NullPointerException [Server:server-one] at com.sun.faces.facelets.tag.TagAttributeImpl.getBoolean(TagAttributeImpl.java:136)

Hello,

We migrate an application from glassfish 4 to Wildfly 10.1.0.

When we use some pages, we have the error below.

We want to avoid modifications of code and want to find a solution with configuration modification.

We suppose the bug it's linked to the JSF Version.

Our application on glassfish use a JSF version 2.1.21 and IceFaces 3.3.

Solutions we have tested (but they fail) :

1) In the wildfly (folder modules) Replace the following jars on jboss and modify the associated module.xml :

wildfly-10.1.0.Final\modules\system\layers\base\javax\faces\api\main

<resource-root path="jboss-jsf-api_2.2_spec-2.2.13.jar"/> ==> <resource-root path="jsf-api-2.1.21.jar"/>

wildfly-10.1.0.Final\modules\system\layers\base\com\sun\jsf-impl\main

<resource-root path="jsf-impl-2.2.13.SP1.jar"/> ==> <resource-root path="jsf-impl-2.1.21.jar"/>

2) Add the JAVA_OPT : -Dorg.apache.el.parser.COERCE_TO_ZERO=false

3) Add the JAVA_OPT : -Dorg.apache.el.parser.COERCE_TO_ZERO=true

4) Combination of solutions 2 or 3 with the solution 1

5) Implement the ElResolver

public class EmptyToNullStringELResolver extends ELResolver { @Override public Class<?> getCommonPropertyType(ELContext context, Object base) { return String.class; } @Override public Object convertToType(ELContext context, Object value, Class<?> targetType) { if (value == null && targetType == String.class) { context.setPropertyResolved(true); } return value; } @Override public Iterator<FeatureDescriptor> getFeatureDescriptors(ELContext context, Object base) { return null; } @Override public Class<?> getType(ELContext context, Object base, Object property) { return null; } @Override public Object getValue(ELContext context, Object base, Object property) { return null; } @Override public boolean isReadOnly(ELContext context, Object base, Object property) { return true; } @Override public void setValue(ELContext context, Object base, Object property, Object value) { // NOOP. } }

And register it in faces-config.xml as below:

<application>
    <el-resolver>com.example.EmptyToNullStringELResolver</el-resolver>
</application>

The error we have when we deploy our application without any modification in the conf of wildfly :
