FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

Confirmed on Solaris 8 with JDK 1.4.

A DESCRIPTION OF THE PROBLEM :
LogManager documentation says:
<ul>
 <li>"java.util.logging.config.class"
 <li>"java.util.logging.config.file"
 </ul>
 These two properties may be set via the Preferences API, or as
 command line property definitions to the "java" command, or as
 system property definitions passed to JNI_CreateJavaVM.

It does not say how to set java.util.logging.config.class
using the Preferences API, and doesn't work for all the
obvious ways of using the Preferences API.

I have looked through the source code for LogManager and it
doesn't look like it is even trying to use the Preferences
API as documented.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run code

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected:
LogManager.readConfiguration() should report an error in trying to
load "Non Existent Class!".

Actual:
No error is reported, even though the program confirms that
the java.util.logging.config.class is set to "Non Existent Class!"
and "/Non /Existent /Class!" appears in the registry


This bug can be reproduced always.

      Preferences.systemRoot().get("java.util.logging.config.class",
                                   "Pref Not Found!"));

      // make sure that it is trying to use the new class
      LogManager.getLogManager().readConfiguration();
    }
    catch (IOException ex) {}
  }
}

CUSTOMER WORKAROUND :
use System properties instead of Preferences
