Spring Actuator Changes Upgrading From Spring Boot 2.4.3 to 2.6.2

We have a Spring Boot web application developed with Spring Boot 2.4.3 and deploys Spring Actuator. I am investigating upgrading to Spring Boot 2.6.2 and have the majority of the issues working. I removed spring actuator starter from the project and war file and it deploys and runs fine. We are running using Java 11 and Wildfly 18.
If I add the spring actuator starter back into to the project pom file and war file pom files, it shows the following warning during deployment:

I went down the path of trying to add jar files to the project for the missing class, but the problem adds to another missing class file. I could not find any major changes in Spring Actuator between Spring Boot versions 2.4.2 and 2.6.2 that would cause this problem.
Does anyone have any insight into changes in Spring Boot that might cause the deployment issue?

Jboss Nested Dependencies for EAR Deployment

I'm working on an EAR that will be deployed to a jboss wildfly server. There is a bunch of common code that gets shared between different projects that the ear depends on. That code gets packaged into a jar and placed into the lib directory of the EAR. So far so good, but as soon as I go to deploy I run into problems. 'Common.jar' has its own set of dependencies which the classloader doesn't seem to be able to locate. When I try to start up my server I get the following error:

I have tried everything I can think of any nothing seems to help. All of the docs and information I have found so far are for dependencies on jboss modules. How do I set up a dependency on a third-party library nested in a jar?

ClassNotFoundException jdk.net.* in Wildfly

My app just started blowing up on startup after upgrading to latest MongoDB drivers. Using Wildfly 19, JDK14, and I've confirmed that at compile time jdk.net.* are available. Clearly they're either not making it into the runtime environment or there is a security issue. My guess is that the module is being blocked, but I've not been able to figure out how to get access to it.
Log output:

Figured it out. In the Wildfly standalone.xml file add
<global-modules>
<module name="jdk.net" slot="main" />
</global-modules>
inside of the block

Using Wildfly 10.1, JDK 8. Adding the following block to the file jboss-deployment-structure.xml inside the dependencies section solved the problem.
<system export="true">
<paths>
<path name="jdk/net"/>
</paths>
</system>

JBoss EAP 7.1 Deployment Failed Integrator: Provider not found

We are migrating our applications from JBoss EAP 6.x.x to JBoss EAP 7.1. I have made all the required configurations on my JBoss 7. But while deploying one application on Jboss 7.1 I'm getting following error on admin console :

My Deployment structure :
project-services.ear
+++ lib
+++ META-INF
+-- proj-impl.jar
+-- proj-domain-ejb.jar
com.comp.pack.enterprise.domain.util.CustomEnversIntegrator is
Custom Integrator which is part of jar present in lib folder.

The issue was with the hibernate version provided by JBoss EAP 7.1. I was using Hibernate 3 in my code and JBoss 7.1 provides hibernate 5.1 by default. By updating my code according to Hibernate 5.1, I was able to resolve this issue.

I am having porblem in finding out the jar for this class. Should it be in my JDK or some third party web service library?
We are using resteasy in the project but I cannot find this class in resteasy jar either.
Note: We are not using Apache CXF.
Any help would be appreciated.
Thanks.

Are you using maven build tool for packaging your application?
I guess you've got to include an appropriate 3rd party jar into your build.
For maven it look like
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.0.1</version>
</dependency>
For any other build tools(gradle,SBT) you can visit
https://mvnrepository.com/artifact/javax.ws.rs/javax.ws.rs-api/2.0.1
