JDK 9: JUnit 5 test compile with SpringExtension produces java.lang.NoClassDefFoundError: org/w3c/dom/ls/DocumentLS

Question

I believe this problem not to be related to module exclusions in JDK 9 (as with java.se.ee), but rather with the fact that JDK 9 includes a newer version of org.w3c.dom.ls i

Answer 1

From what I can tell, DocumentLS is from a 2002 draft of the W3C API, it doesn't appear to have made it into a released version. It looks like xerces-2.4.0 (from 2006?) includes it but newer versions don't. So upgrading to a more recent Xerces may be needed here. If Spring really depends on DocumentLS then it will need to be updated too.
