Binary distribution includes storm-kafka-monitor source/javadoc in toollib directory

Quoting Alexandre's RC3 vote:

I hate to be the one who always give bad news, but as a matter of
facts, Storm 1.2.0 RC3 installation from binary artifacts (both
apache-storm-1.2.0-src.tar.gz and apache-storm-1.2.0.zip) leads to "by
default KO Kafka monitor" in Nimbus UI (which dirty exceptions in
ui.log)

Here's for example what I get from apache-storm-1.2.0-src.tar.gz
downloaded from
https://dist.apache.org/repos/dist/dev/storm/apache-storm-1.2.0-rc3/apache-storm-1.2.0-src.tar.gz:

$ tar ztvf apache-storm-1.2.0.tar.gz apache-storm-1.2.0/toollib
-rwxrwxrwx ptgoetz/staff 16999 2018-02-06 21:22
apache-storm-1.2.0/toollib/storm-kafka-monitor-1.2.0-sources.jar
-rwxrwxrwx ptgoetz/staff 93461 2018-02-06 21:22
apache-storm-1.2.0/toollib/storm-kafka-monitor-1.2.0-javadoc.jar
-rwxrwxrwx ptgoetz/staff 21591320 2018-02-06 21:22
apache-storm-1.2.0/toollib/storm-kafka-monitor-1.2.0.jar

And here's what I see in ui.log:

Deleting the extraneous storm-kafka-monitor-1.2.0-sources.jar and
storm-kafka-monitor-1.2.0-javadoc.jar file, then restarting Nimbus
solves the issue.

However, binaries artifacts should be as clean as possible, isn't it ?
