Summary: NullpointerException
Product: SLF4J
Version: unspecified
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: critical
Priority: P2
Component: Core API
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Logger logger = LoggerFactory.getLogger("com.mycompany");
String[] parameters = null;
logger.debug("Parameters are {}", parameters);
will throw a NullPointer exception as follows :
Exception in thread "main" java.lang.NullPointerException
at
org.slf4j.helpers.MessageFormatter.arrayFormat(MessageFormatter.java:136)
at org.slf4j.impl.Log4jLoggerAdapter.debug(Log4jLoggerAdapter.java:223)
Obviously the compiler binds the debug method to : logger.debug(format, new
Object[])
and to get around this we have to force the other method by using a typecast :
String[] parameters = null;
logger.debug("Parameters are {}", (Object)parameters);
Is there some better way around this ambiguity?
