Could it be that you are telling Jakarta Commons Logging (JCL) to use SLF4J and telling SLF4J to use JCL ?
I never tried that :-) but I guess it would result in an endless loop, hence the StackOverflowError. Please, check if you have both slf4j-jcl.jar and jcl104-over-slf4j.jar on your classpath. Logging can be so funny !
