           Summary: JUL-toSLF4J-Bridge missing FINE, FINER and FINEST
                    messages
           Product: SLF4J
           Version: 1.5.x
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: major
          Priority: P2
         Component: Unspecified
        AssignedTo: dev at slf4j.org
        ReportedBy: florian.pepping at wincor-nixdorf.com


Is state:
Using the JUL-to-SLF4J-Bridge, only messages with a Level of INFO or higher are
logged. All other messages are discarded.

Should be state:
Using the JUL-to-SLF4J-Bridge, all messages according to the
logback-configuration should be logged.

Cause:
During initalization of the JUL-to-SLF4J-Bridge, the JUL-Logging configuration
is resetted. During this operation the level of the root-Logger of JUL is set
to the default-level of INFO (see Javadoc for reference).

Solution:
After resetting, the loglevel of the root-logger must be set to Level.ALL, so
that JUL logs all messages and the SLF4J-Framework can decide what to log.

Code:
change the install()-method of the SLF4JBridgeHandler from
##############
public static void install()
{
 LogManager.getLogManager().reset();
 LogManager.getLogManager().getLogger("").addHandler(new SLF4JBridgeHandler());
}
##############
--> to
##############
public static void install()
{
 LogManager.getLogManager().reset();

 java.util.logging.Logger logger = java.util.logging.Logger.getLogger("");
 logger.setLevel(Level.ALL);

 LogManager.getLogManager().getLogger("").addHandler(new SLF4JBridgeHandler());
}
