css4j v3.5.2
Build fixes
The previous 3.5.1 version was producing correct Maven metadata, but the generated Gradle metadata was incorrect (it advertised a minimum required version of Java 11).
Even if you use Apache Maven to build your project, you may have downstream users with Gradle builds. If you are using css4j 3.5.0 or 3.5.1 you are encouraged to upgrade to 3.5.2.
