@srowen the case I'm concerned about is the following. Someone wants to map
SLF4J to JUL, so they'd need to remove the "jul-to-slf4j" dependency otherwise
they'll get a routing loop. But then spark won't compile because this code
depends on the `SLF4JBridgeHandler` which exists only in the "jul-to-slf4j"
jar. Am I missing something, or won't this cause a compile error for a user in
that situation?
