This is probably because Java 9 and later have removed a number of modules that were part of Java 8 and earlier. You can re-include them by running java with --add-modules java.xml.bind. I don’t use boot myself, but from looking at the docs, it sounds like you should be able to do this by setting export BOOT_JVM_OPTS="--add-modules java.xml.bind" (OS X and Linux). For Windows it’s a little more complicated: you have to create a boot.l4j.ini file in the same directory as your boot.exe, and inside the file, put the --add-modules java.xml.bind directive. See also https://stackoverflow.com/questions/43574426/how-to-resolve-java-lang-noclassdeffounderror-javax-xml-bind-jaxbexception-in-j if you’d like more details about the underlying Java problem that this fixes.
