See http://www.slf4j.org/faq.html#IllegalAccessError
This error is caused by the static initilizer of the LoggerFactory class > attempting to directly access the SINGLETON field of > org.slf4j.impl.StaticLoggerBinder. While this was allowed in SLF4J 1.5.5 > and earlier, in 1.5.6 and later the SINGLETON field has been marked as > private access. > > If you get the exception shown above, then you are using an older version > of slf4j-api, e.g. 1.4.3, with a new version of a slf4j binding, e.g. 1.5.6. > Typically, this occurs when your Maven *pom.ml* file incoprporates > hibernate 3.3.0 which declares a dependency on slf4j-api version 1.4.2.
