You can do what other people suggest which is to exclude xml-apis which worked fine with me, but if your are using and an old jaxb-api replace them with jakarta.xml.bind-api:
jakarta.xml.bind
jakarta.xml.bind-api
2.3.3
and of course upgrade your jaxb-impl to match the same api:
com.sun.xml.bind
jaxb-impl
2.3.3
