ClassNotFoundException: javax.xml.bind.*

The java.xml.bind package is deprecated in Java 9 and not included in the default classpath. Code which tries to use classes under java.xml.bind.* will throw ClassNotFoundException. For example, from clavatar:

java.lang.ClassNotFoundException: javax.xml.bind.annotation.adapters.HexBinaryAdapter

The fix, as described in How to upgrade your Clojure projects to use Java 9, is to add the JVM option --add-modules "java.xml.bind". In a Leiningen project.clj file, this is:

:jvm-opts ["--add-modules" "java.xml.bind"]

Libraries affected by this:

• clavatar (Gravatar URL generator)

ClojureScript used to import that package, fixed as of clojure/clojurescript@544c1b7
