>
> org.apache.logging.log4j.jul.ApiLogger doesnt behave the same depending where
> we come from (logger.info() vs logger.log() typically)
> The main difference is the message factory used.
> for this statement:
> {code}
> logger.info("{foo}");
> {code}
> a SimpleMessage will be emitted but for
> {code}
> logger.log(recordWithSameContent);
> {code}
> a MessageFormatMessage will be emitted making the log statement failling.
> org.apache.logging.log4j.jul.ApiLogger#log(java.util.logging.LogRecord)
> should be reworked to handle such a case.
> Here how to reproduce it:
> {code}
> Logger.getLogger("foo").info("{test}");
> Logger.getLogger("foo").log(new LogRecord(Level.INFO, "{test}"));
> {code}
> The fix is as simple as testing
> org.apache.logging.log4j.jul.ApiLogger#log(java.util.logging.LogRecord) and
> if null don't call logger.getMessageFactory().newMessage(record.getMessage(),
> record.getParameters()) but
> logger.getMessageFactory().newMessage(record.getMessage())
