Milo OPC-UA Client NoSuchMethod error with io.netty.buffer.ByteBuf.writeMediumLE(int)

I downloaded the sample code from GitHub and modified the ReadNodeExample.java just to make sure that I can connect to an OPC Server (not Milo, it's a C#-based OPC Server). I was able to verify that the sample code is able to read/write/call nodes from my server with the modifications.
I then reimplemented what I thought I needed into my actual project, but I might be missing something since I cannot connect under this project and receive the following error:
java.lang.NoSuchMethodError: 'io.netty.buffer.ByteBuf io.netty.buffer.ByteBuf.writeMediumLE(int)'
This error happens in the ClientExampleRunner.run() while running createClient()
I can still run the sample project and still connects.
Here's my pom.xml:
The org.milo is added near the end and I added what I saw was added from the sample (included ch.qos.logback and jetbrains). Then added the io.netty thinking it would help, but still have the same error.

My modification to the KeyStoreLoader/ClientExampleRunner. I modified the name to match my application (even in the sample) but the most notable change is that I resolve the name of the machine dynamically
String hostName = InetAddress.getLocalHost().getHostName();
...
SelfSignedCertificateBuilder builder = new SelfSignedCertificateBuilder(keyPair)
.setCommonName("...")
.setOrganization("...")
.setOrganizationalUnit("eng")
.setLocalityName("...")
.setStateName("...")
.setCountryCode("...")
.setApplicationUri("urn:" + hostName + ":OpcServer")
.addDnsName("localhost")
.addIpAddress("127.0.0.1");
In the ClientExample, I only changed the EndpointUrl.

It seems that your actual project has an old version of Netty somewhere on its classpath.
ByteBuf::writeMediumLE (and all the other LE-suffixed ByteBuf methods) were introduced in Netty 4.1.

I know this is not the best formulated question but i dont know what else to do...

I followed instructions in Comment by Piotr P. Karwasz. That worked out fine! The problem with one of the solutions i tried was the version number.

Getting a 403 for static resources in spring boot without using spring security

I have a spring boot application that is not using spring security at all, and when some requests come through for static resources, the server returns a 403.
The spring boot application is running in a tomcat 9 server (not embedded). A lot of the requests triggering the 403 come from mobile devices. I have read a lot of articles about this issue but they all refer to the spring security implementation which I am not using.
Has anyone experienced this? Any help/suggestions would be greatly appreciated.

I ran the application as standalone (without external Tomcat) and the problem does not seem to occur. This is pointing more to an interaction between the two or tomcat 9 configuration issue.

The problem was a tomcat 9 mis-configuration with a security realm and had nothing to do with Spring. The security real was not connecting to the user database so it was blocking anything static.

Why Vaadin-maven-plugin run with multiple versions?

I have a maven project with vaadin 14.1.25 and Java EE 7 which creates a .war file.
When I run or build project I see different version of vaadin-maven-pluging is proceeding.
Such as in attached picture below:
1. vaadin-maven-pluging: 14.1.17
2. vaadin-maven-pluging: 14.1.19
3. vaadin-maven-pluging: 15.0.0
I have only one maven plugin in my project which is vaadin-maven-pluging: 14.1.25.
Can someone explain why does it happen?

Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/applicationContext.xml];

In my pom.xml I am getting the following error. The reason why I have <version>2.0.3</version> is to use Spring 2 NTLM authentication.
org.springframework.beans.factory.BeanDefinitionStoreException:
Unexpected exception parsing XML document from
ServletContext resource [/WEB-INF/applicationContext.xml]; nested exception
is java.lang.NoSuchMethodError:org.springframework.aop.config.AopNamespaceUtils.

Edit 1
As per PSR's suggestion, the error occurs when the following dependency is added
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>2.0.3</version>
</dependency>

The problem will come because of one of the dependency.Try to remove all dependencies first what you shown.Then try to add one by one then we can find out the problem where it is

Check for multiple version for spring jars in your class path. we have spring-dao and spring-tx in class path. removing spring-dao fixed issue.
