           Summary: [logging] call to getClassLoader() in LogFactoryImpl not
                    checked for null
           Product: Commons
           Version: 1.0.4
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Logging
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: luke.sleeman@ordermate.com.au


In line 374 of LogFactoryImpl.java getClassLoader() is called:

logInterface = this.getClass().getClassLoader().loadClass(LOG_INTERFACE);

However, the docs for getClassLoader() state that some implementations may use
null to return the system classloader.  This occurs under CrEme a JVM for the
PocketPC platform which some of our products run under, causing a null pointer
exception.  Perhaps it would be better to change line 374 to read:

logClass = loadClass(LOG_INTERFACE);

which seems to solve the problems I have been having.  At any rate calls to
getClassLoader() should be checked to ensure that they haven't returned null.

In addition the error that I got:
org.apache.commons.logging.LogConfigurationException:
org.apache.commons.logging.LogConfigurationException:
java.lang.NullPointerException (Caused by java.lang.NullPointerException)
(Caused by org.apache.commons.logging.LogConfigurationException:
java.lang.NullPointerException (Caused by java.lang.NullPointerException))

Certianly wasnt very helpfull for figuring out what is going on.
