[slf4j-user] logging a stack trace along with a parameterized string

[Ceki Gulcu]

Hi Lowell,

This is a well-known shortcoming of the SLF4J API. However, since exceptions are 
by definition rare, you can write

LOG.debug("Got a "+e.getClass().getName()+" with value "+ e.getValue(), e);

with an *infrequent* loss in performance. Of course, this form is also less 
pleasant to write, but again you write less of these.

HTH,
