In case you are specifying a Java toolchain
to compile your Java files with a higher version of Java than the one running Gradle, GWT compilation might fail.
This allows plugins users to avoid that -- I made it configurable since I'm not sure if that's a good idea by default (e.g. the someone may want to run Gradle and GWT in Java 11 and default Java compilation in Java 8 ...)
