Bug#905359: libhibernate-validator-java: FTBFS with Java 11 due to xjc removal

[Emmanuel Bourg]

Package: libhibernate-validator-java
Severity: important

User: debian-java at lists.debian.org
Usertags: default-java11

libhibernate-validator-java calls the xjc tool in its debian/rules file,
but xjc has been removed from Java 11. The package should now use the
maven-jaxb2-plugin or the standalone jaxb package providing xjc
independently of the JDK (once #905357 is fixed).
