IllegalArgumentException deploying CAS 5.3.10 Maven Overlay WAR on Wildfly 14

I'm deploying CAS 5.3.10 on Wildfly 14, using a Maven Overlay as specified in https://apereo.github.io/cas/5.3.x/installation/Configuring-Servlet-Container.html#external and using the project template at: https://github.com/apereo/cas-overlay-template/tree/5.3

I have already edit the pom which deploys correctly on Wildfly 9, but on Wildfly 14 deploy fails with the following exception:

Caused by: java.lang.IllegalArgumentException: object is not an instance of declaring class at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.springframework.core.io.VfsUtils.invokeVfsMethod(VfsUtils.java:100) at org.springframework.core.io.VfsUtils.getFile(VfsUtils.java:172) at org.springframework.core.io.VfsResource.getFile(VfsResource.java:90) at org.apereo.cas.util.CasVersion.getDateTime(CasVersion.java:59) at org.apereo.cas.util.SystemUtils.getSystemInfo(SystemUtils.java:50) ...........

The problem seems to be related to the CasVersion class that attempts to access via VFS (via spring) to retrieve information related last modification date of the module.

Since @Marco didn't provide his fix, I will. For anyone having the same issue follow below steps to resolve:

  1. After checking out cas-overlay-template, create CasVersion.java under src/main/java/org/apereo/cas/util with the following content:
package org.apereo.cas.util;

import lombok.SneakyThrows;
import lombok.experimental.UtilityClass;
import lombok.extern.slf4j.Slf4j;
import org.springframework.core.io.VfsResource;

import java.io.File;
import java.net.URL;
import java.time.ZonedDateTime;


/**
 1. Class that exposes the CAS version. Fetches the "Implementation-Version"
 2. manifest attribute from the jar file.
 3.  4. @author Dmitriy Kopylenko
 4. @since 3.0.0
 */
@Slf4j
@UtilityClass
public class CasVersion {

    /**
     * @return Return the full CAS version string.
     * @see java.lang.Package#getImplementationVersion
     */
    public static String getVersion() {
        return CasVersion.class.getPackage().getImplementationVersion();
    }

    /**
     * Gets specification version from the manifest package.
     *
     * @return the specification version
     */
    public static String getSpecificationVersion() {
        return CasVersion.class.getPackage().getSpecificationVersion();
    }

    /**
     * Gets last modified date/time for the module.
     *
     * @return the date/time
     */
    @SneakyThrows
    public static ZonedDateTime getDateTime() {
        final Class clazz = CasVersion.class;
        final URL resource = clazz.getResource(clazz.getSimpleName() + ".class");
        if ("file".equals(resource.getProtocol())) {
            return DateTimeUtils.zonedDateTimeOf(new File(resource.toURI()).lastModified());
        }
        if ("jar".equals(resource.getProtocol())) {
            final String path = resource.getPath();
            final File file = new File(path.substring(5, path.indexOf('!')));
            return DateTimeUtils.zonedDateTimeOf(file.lastModified());
        }
        // These lines are causing the reported exception so we just comment them out.
        // if ("vfs".equals(resource.getProtocol())) {
        //     final File file = new VfsResource(resource.openConnection().getContent()).getFile();
        //     return DateTimeUtils.zonedDateTimeOf(file.lastModified());
        // }
        LOGGER.warn("Unhandled url protocol: [{}] resource: [{}]", resource.getProtocol(), resource);
        return ZonedDateTime.now();
    }
}
  1. Add below dependencies to pom.xml
    <!-- Required for lombok imports -->              
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.16.16</version>
        <scope>provided</scope>
    </dependency>  
    <!-- Required for DateTimeUtils to be available on classpath -->              
    <dependency>
        <groupId>org.apereo.cas</groupId>
        <artifactId>cas-server-core-util</artifactId>
        <version>${cas.version}</version>
    </dependency>
  1. Replace any occurrences of <app-server>-tomcat</app-server> with <app-server></app-server> since you gonna provide application server.

Above steps should be enough to resolve the reported issue.

as leopal says,It's work. I compiled the Java file above and replaced it with a JAR package I tried to replace the cas-server-core-util-api-5.3.16.jar version of the JAR package.
