> The system class default defined in ApplicationClassLoader has "javax.". This
> is too broad. The intent of the system classes is to exempt classes that are
> provided by the JDK along with hadoop and minimally necessary dependencies
> that are guaranteed to be on the system classpath. "javax." is too broad for
> that.
> For example, JSR-330 which is part of JavaEE (not JavaSE) has "javax.inject".
> Packages like them should not be declared as system classes, as they will
> result in ClassNotFoundException if they are needed and present on the user
> classpath.
