Hi Carl,
Thank you for your detailed message.
It's a bug in the EnvUtil class which wrongly assumes that the
classloader for the EnvUtil class cannot be null. However, per the
javadocs of the Class.getClassLoader method:
Some implementations may use null to represent the bootstrap class
loader. This method will return null in such implementations if this
class was loaded by the bootstrap class loader.
Could you please file a jira issue report for this bug? A github pull
request would also be appreciated, although not strictly necessary.

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
