Hi,

Problem description:
"Class path contains multiple SLF4J bindings" message appears in WebLogic 10.3 log during startup of an application with SLF4J 1.5.8.
The problem is that exactly the same binding is printed twice and therefore the warning is irrelevant:
SLF4J: Found binding in [zip:/servers/WLServer/tmp/_WL_user/MyApplication/he3hgg/epc.jar!/org/slf4j/impl/StaticLoggerBinder.class]

Suggested solution:
In org.slf4j.LoggerFactory.singleImplementationSanityCheck() method in line 192 getResources somehow returns 2 exactly the same bindings:
Enumeration paths = LoggerFactory.class.getClassLoader().getResources(
STATIC_LOGGER_BINDER_PATH);

So using Set implementationSet = new HashList();
in line 194 instead of List implementationList = new ArrayList();
will solve such irrelevant warning.
