logging UI stops working when additional handlers defined

[Grzegorz Sobczyk]

I run solr on tomcat with configured JUL to log solr to separate file:

org.apache.solr.level = INFO
org.apache.solr.handlers = 4solrerr.org.apache.juli.FileHandler

​I've noticed that logging UI ​stops working. Is it normal behavior or is
it bug?
(When cores are initialized JulWatcher is registered only for root logger.)
