[logback-user] logging arrays?

[Jeff Jensen]

Thanks for trying and verifying!

And I'm using the same slf4j, but 0.9.17 logback.
I entered a defect item to start with...
http://jira.qos.ch/browse/LBGENERAL-36

I can reproduce your description. 

23:48:28.486 [main] DEBUG logback.LogArrayTest - the array=[1, 2, 3, 4, 
5, 6, 7, 8]
23:48:28.559 [main] DEBUG logback.ParameterizedTypeTestClass - 
genericSuperClass=logback.ParameterizedTypeTestClass<java.lang.Long, 
java.lang.Object>
23:48:28.559 [main] DEBUG logback.ParameterizedTypeTestClass - 
ActualTypeArguments=class java.lang.Long
23:48:28.560 [main] DEBUG logback.ParameterizedTypeTestClass - 
ActualTypeArguments array count=2
23:48:28.560 [main] DEBUG logback.ParameterizedTypeTestClass - 
type=class java.lang.Long
23:48:28.560 [main] DEBUG logback.ParameterizedTypeTestClass - 
type=class java.lang.Object

The tricky code is:

        Type[] types = genericSuperClass.getActualTypeArguments();
        LOG.debug("ActualTypeArguments={}", types);
        // only displays the first element:
        // ActualTypeArguments=class java.lang.Long

        LOG.debug("ActualTypeArguments array count={}", types.length);
        for (Type type : types) {
            LOG.debug("type={}", type);
        }

This is with slf4j 1.5.8 and logback 0.9.15
