[logback-user] Problem with Groovy detection in Glassfish 3.1.2.2

[Karl Spies]

Hi,

my goal is to use slf4j and logback in our Glassfish servers. But I
came a cross with an error in the groovy detection. Please see the
stacktrace below.

I think the problem has something to do with the classloader in
glassfish. The libraries are placed in the root lib/endorsed folder. I
need them there to have the highest priority while classloading.

Is this a problem with my setup and idea, or do I encountered a real
misbehavior.

I attached a patch within this mail.

Thanks in advance.

Best Regards

Karl
