Summary: Log4j2's SimpleLogger Implementation Issue for var args
method's
Key: LOG4J2-811
URL: https://issues.apache.org/jira/browse/LOG4J2-811
Project: Log4j 2
Issue Type: Bug
Components: API
Affects Versions: 2.0.1
Reporter: Yogesh Rao
There seems to be an issue with SimpleLogger implementation provided by log4j2.
The issue seems to be in the new improved API supporting placeholders and var
args when called with an Object Array of size 0.
for e.g logger.error("Hello World {} in {} " , new Object[0]);
A statement above results in an error as shown below
ERROR StatusLogger Unable to locate a logging implementation, using SimpleLogger
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1

Solution to place a check in SimpleLogger for checking the size of the array .
