OK, I can change JDK per module. Now I cannot build log4j-jmx-gui since the class com.sun.tools.jconsole.JConsolePlugin (used in our ClientGuiJConsolePlugin) doesn't seem to work with JDK 9. I tried to set that module to JDK 7, but it doesn't help.
It is not good that we break a popular IDE like IntelliJ IDEA in this way. That might scare away potential developers.
