How to convert XML to String with JAXB and spring-boot?
When I run a mvn spring-boot:run on the folder that has the pom.xml file the application starts and serializes a POJO into a XML correctly, but when I do it by going to the target folder and starting it by using java -jar in the jar file I get javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath caused by .java.lang.ClassNotFoundException: com.sun.xml.internal.bind.v2.ContextFactory.
In my maven I have the following JAXB dependencies:
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.1</version>
</dependency>
<dependency>
<groupId>org.glassfish.jaxb</groupId>
<artifactId>jaxb-runtime</artifactId>
<version>2.3.1</version>
<scope>runtime</scope>
</dependency>
Here's the method that serializes a POJO into XML:
private static final Pattern REMOVE_HEADER = Pattern.compile("\\<\\?xml(.+?)\\?\\>");
public static String toXML(final Object data) {
try {
final var jaxbMarshaller = JAXBContext.newInstance(data.getClass()).createMarshaller();
jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
final var sw = new StringWriter();
jaxbMarshaller.marshal(data, sw);
return XMLUtils.REMOVE_HEADER.matcher(sw.toString()).replaceAll(StringUtils.EMPTY).strip();
} catch (final JAXBException e) {
XMLUtils.LOGGER.error("Error while converting POJO to XML. ERROR: {}.", e.getMessage(), e);
}
return "";
}
Here's the log when I start the application with java -jar:
javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath.

I am using java 11 and I am aware that in java 11 JAXB was removed from the SE JDK because it is considered as a EE feature.
I am not able to execute it using mvn spring-boot:run in production environment because of the size of the docker image and security related issues using docker container.
Since Spring Boot generates a fat jar, shouldn't the application run with java -jar applied to the spring boot fat jar generated file the same way as it does with mvn spring-boot:run inside the folder with pom.xml?
EDIT:
After a lot of digging and testing I found that the problem occurs when we try to marshall several valid POJOs using parallel stream instead of stream on the POJOs list. I uploaded the code in java-eleven-jaxb-hell to better understanding, unfortunatelly I cannot change parallelStream to stream because of performance issues. Just to remember, for the problem to happen you have to run java -jar against spring-boot generated fat jar in target folder.
