> {{JULLogger.getLevel()}} fails with a {{NullPointerException}} if the JUL root logger has a {{null}} level. This is a common situation in JDK 8+, since {{LogManager$RootLogger}} does not set the log level any more in its constructor.
> A practical example where it fails is Tomcat's {{ClassLoaderLogManager}}: cf. [BZ 66184|https://bz.apache.org/bugzilla/show_bug.cgi?id=66184].
