[logback-dev] Eclipse plugin

All right, this is exactly what I think is happening. In fact of that, if
you put a call to the toString() method explicitly in the log line, the
eclipse plugin works right:

private Logger log = LoggerFactory.getLogger(
TestingLogback.class.getSimpleName());

Car car = new Car("Mercedes")
Integer aNumber = new Integer(2);
log.debug("A correct log line: {}", aNumber);
log.debug("A failed log line: {}", car.toString()); <--------- toString()
method called
log.debug("This line is unreachable for the logback plugin");

In this case, the eclipse plugin shows this output:

A correct line: 2
A failed log line: Mercedes
This line is unreachable for the logback plugin

Your proposal for the resolution seems to be reasonable. Let's see what the
developers think...
