Switch from Java 8 to Java 11 in my IntelliJ gradle project, a issue comes at runtime

I was using Java 8 for my gradle project, now I installed Java 11 & try to switch to using Java 11.
My Java 11 version details:
My gradle project has following configuration in build.gradle file:
plugins {
id 'org.springframework.boot' version '2.5.3'
id 'io.spring.dependency-management' version '1.0.11.RELEASE'
id 'java'
}
group = 'com.my.webapp.xi'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'
repositories {
mavenCentral()
}
...
...
As you can see above I have sourceCompatibility = '11' now, it used to be sourceCompatibility = '8'.
In my IntelliJ Project strucutre settings, I have chosen Java 11 instead of 8 as well:
There is no issue building the project. But when I run my java gradle project my Intellij gives me this error:
If above screenshot error is not enough, here is the complete error message from Intellij:
> Process 'command '/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1
When I was using Java 8 (in both build.gradle & the settings of Intellij) it was fine without any issue but when I switch to Java 11 this issue comes,
I also tried switching to Java 16, I get the same issue.
What am I missing? What could be the reason? Where should I check?

After I restarted my IntelliJ, the error disappeared.
#akortex, I would like to take a screenshot to convince you that line of error is the only message on console. But I can't reproduce it anymore. If I misunderstand you, it would be nice if you could tell more about "full error", do you mean some other places to check the error or use some command with verbose flag?

Alpine Docker Image to run JLink executable

My current Docker image is approximately 200MB. My goal is to reduce that as much as possible, so I thought the alpine image would be a great way to achieve that. However, I keep encountering roadblocks.
It's a multi-module libGDX project that uses Java 14 and its preview features, along with JLink (from JPackage) to produce a custom (lightweight) JRE.
I only care to deploy the server module, which depends on the common module (which the client module also uses).
I'll be providing all the necessary files below, but in case I'm missing something, here is a link to the repo: https://github.com/payne911/marvelous-bob/tree/dev
Current problem
I either get:
when executing ./server: file not found for an executable file which I know exists and is executable where I'm trying to run it in the Docker Image
when executing apk add --no-cache someLibrary: a segfault: core dumped when trying to download libraries in my ENTRYPOINT which I thought were required to execute that file (libstdc++ and libc6-compat)
Goal
Reusable lightweight Docker Image which contains everything to run libGDX executables generated by JLink.
Current files which are in a working state and I'm trying to refactor

#deduper seems to have figured it out (see https://chat.stackoverflow.com/rooms/222569/discussion-between-deduper-and-payne), but I didn't have time to go back and make sure his analysis is right.
In theory, it does make a lot of sense, so I'm posting it nonetheless as an answer:
I'm pretty sure the main cause of the errors you describe in your question is because you built the runtime on either Windows 10 or Ubuntu; then tried to deploy and run the runtime on Alpine.
I won't accept my answer because I haven't made a confirmation of this yet, but I'm nonetheless posting it in case others encounter this problem and want a probable clue.

Spring boot 2 Address already in use

I have a spring boot application which is a cron job that runs daily.
I recently migrated my spring boot application to 2.1.6 from 1.5.10 and Java from 8 to 11.
When deployed in the server this app is throwing an Exception:
java.net.BindException: Address already in use
It was working fine on the lower version.
I made sure there is no other services running on the port 8590.
Below is my gradle file:

I have the port specified in my application.properties
server.port=8590
I tried with the below property as well that did not work
management.server.port=8590
management.endpoints.web.exposure.include=*
management.endpoint.shutdown.enabled=true
endpoints.shutdown.enabled=true
Any hints would be greatly appreciated.
EDIT :
I tried killing the PID of this service and triggered startup script. I did work and for the next execution it thrown the same error again.
Looks like somehow shutdown has to happen after each execution.
srartup.sh
nohup /opt/jdk-11.0.2/bin/java -Xmx768m -Xms256m -Dlogging.config=/opt/runnables/alerts-service/logback.xml -jar /opt/runnables/alerts-service/alerts-service.jar --spring.profiles.active=qa &> logs/console.log&

Check which process is using the port,
In windows
netstat -ano | find "8080"
In linux
netstat -nap | grep 8080
If someone else is using that port, you have to use another port or kill that other process and let the port free.

Finally I found the solution. By adding the application context closing tag has worked for me in main class.
SpringApplication.run(AlertsApplication.class, args).close();

I'm building the project using gradle 4.8 and java version "1.8.0_171".
Any help will be appreciated

You are using an arm64 JDK, which may not be your current hardware platform. You should reinstall JDK with platform x86_64 or other which fits your hardware.
Also, it seems you are using Linux, then you may use package manager to install the correct version of JDK and JRE automatically, like sudo apt install openjdk-8-jdk. (It doesn't matter to use OracleJDK or OpenJDK)

gradle refers java 6 even though my java home is aim to java 8

I run ./gradlew clean build
and i get this error:
warning: [options] bootstrap class path not set in conjunction with -source 1.6
/Users/eladb/WorkspaceQa/java/UsersServer/src/test/java/linqmap/users/jms/UsersServerAccessPropUserNameTest.java:163: error: diamond operator is not supported in -source 1.6

(use -source 7 or higher to enable diamond operator)

even though I see my java home is java 8.
where else do i need to configure java 8 ?
➜ myServer echo $JAVA_HOME

sourceCompatibility = 1.8

repositories {

jcenter()

It looks like you've explicitly set the source compatibility.
Try adding:
sourceCompatibility = 1.8
