Cannot load spring context inside a custom PrinterJob - spring

Question

I want to create a custom PrinterJob class that uses Springframework:
public class HelloWorldPrinterJob extends PrinterJob {
// ...
public void print() throws PrinterException {
ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
System.out.println(context.getBean(HelloWorldBean.class));
}
// ...
// for testing purpose
public static void main(String[] args) throws PrinterException {
System.setProperty("java.awt.printerjob", "com.example.HelloWorldPrinterJob");
PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.print();
}
}
I use this pom.xml in order to have all dependencies available inside the target folder:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<!-- ... -->

<packaging>jar</packaging>

<dependency>

</goals>
<configuration>
<outputDirectory>${project.build.directory}</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
Then I copy all the jars that were generated to the endorsed folder of the JRE but when I test the solution I get this error:

I saw that the problem is inside the CachedIntrospectionResults class, in particular because CachedIntrospectionResults.class.getClassLoader() returns null. It is not null when I run the HelloWorldPrinterJob as a standalone application, without placing the classes to the endorsed folder. In case of endorsed case, as I understand CachedIntrospectionResults.class.getClassLoader() returns null because the class was loaded with Bootstrap ClassLoader. Is there a way to bypass this problem?
NOTE: a quick way to test is by running the command inside the project folder
java -Djava.endorsed.dirs=target -cp target\classes com.example.HelloWorldPrinterJob
after
mvn package
