NoClassDefFoundError: javax/xml/bind/annotation/XmlElement with JDK 17 and Jackson 2.13.4

[BharathKumarRavichandran]

Hi folks,
I'm using com.fasterxml.jackson.core:jackson-databind:jar:2.13.4.2 with JDK 17. I have the below dependencies defined in my pom, but somehow I am still getting the below error. It is trying to use JaxbAnnotationIntrospector and javax.xml.bind is one of the dependency in that, but I think that package was deprecated long ago and removed in Java 17. Could somebody help?

    <dependency>
      <groupId>com.fasterxml.jackson.module</groupId>
      <artifactId>jackson-module-jaxb-annotations</artifactId>
      <version>2.13.4</version>
    </dependency>
    <dependency>
      <groupId>com.fasterxml.jackson.module</groupId>
      <artifactId>jackson-module-jakarta-xmlbind-annotations</artifactId>
      <version>2.13.4</version>
    </dependency>

Error:

Java HotSpot(TM) 64-Bit Server VM warning: Sharing is only supported for boot loader classes because bootstrap classpath has been appended

Add a dependency on https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api/2.3.1

Thank you this fixed the issue!

That fixes the issue, but a better long term fix is to stop relying on a deprecated API 😄 All the JAXB annotations have been moved over to the Jakarta project, so you should start using that and start using jackson-module-jakarta-xmlbind-annotations instead.

Proper solution is to just exclude the module:

    private void filterJaxbJavaxModule(Jackson2ObjectMapperBuilder builder) {
        List<Module> modules = ObjectMapper.findModules(Jackson2ObjectMapperBuilder.class.getClassLoader());
        List<Module> filteredModules = modules.stream()
                .filter(m -> !m.getModuleName()
                        .toLowerCase(Locale.ROOT)
                        .contains("jaxb"))
                .peek(m -> log.error("~~~~~ Found Jackson module {}", m.getModuleName()))
                .collect(Collectors.toList());
        builder.modules(filteredModules);
    }
