Logging APIs specification (draft 0.49) states:

"setLevel(String, Level)

... (skipped)

The given log level applies to the named Logger (if it exists), and
on any other named Loggers below that name in the naming hierarchy."

and

"The namespace should typically be aligned with the Java packaging
namespace, but is not required to follow it slavishly."

If any "not follow it slavishly" and define some loggers with
exotic names like ".something" or "something..else" with the
empty parts between dots, then the LogManager will not properly
build its loggers tree as the following test shows.

IMHO, the usage of empty parts of a logger names should be straightly
restricted in the spec and accordingly implemented. Unless to the contrary
it should be straightly permitted in spec and the LogManager namespace
algorithm should be fixed.
