Slf4jLogger wrong formatting in methods with Object arrays

Slf4jLogger in JBoss Logging Manager formats the messages in logging methods with Object array parameters (ie. info(String, Object[]), debug(String, Object[]) etc.) the wrong way. MessageFormatter.format(format, argArray) is used, but MessageFormatter.arrayFormat(format, argArray) should be used instead. Using the format() method results in putting the whole array in the first placeholder and leaving the following ones empty.

Example:

logger.info("1: {} 2: {} 3: {}", new Object[]

);

Expected output:
1: ONE 2: TWO 3: THREE

Actual output:
1: [ONE, TWO, THREE] 2: {} 3: {}
