Ok, I think it is fixed in 1.5.3
with slf4j-simple-1.5.2.jar
Logger log = LoggerFactory.getLogger("test");
log.info("{{}}", "hello");
yields
1 [main] INFO test - {{}}
but with slf4j-simple-1.5.3.jar it yields
1 [main] INFO test - {hello}
soooo, I was wrong. It is fixed in the latest version! (right?)

Hello Jean-Luc,
Could you please describe what you are doing (=code source) and the results
obtained?
For example,
Logger logger = LoggerFactory.getLogger("test1");
logger.info("Hello {{}}");
yields (with slf4j-simple.jar)
0 [main] INFO test1 - Hello {{}}
and
Logger logger = LoggerFactory.getLogger("test2");
logger.info("Hello {{}}", "world");
yields (with slf4j-simple.jar)
0 [main] INFO test2 - Hello {world}
Does the above differ from what you observe or are you trying to do something else?
Cheers,
