I noticed something interesting.
I am dynamically instantiating a component with a call like this:
Factory factory = builder.getFactory();
Map criteria = factory.createDefaultCriteria();
criteria.put("merlin.deployment",
"artifact:block:components/my-component-0.0.1");
criteria.put("merlin.deployment.timeout", "0");
factory.create( criteria );
My component works fine.
Then I add the jars from avalon/logging to my classpath and I get the error
below. Took me a long time to figure out that there was a relationship with
logging, since nothing of the sort is mentioned in the error messages. Also,
because the error is misleading, I'm not able to figure out how to proceed.
It's no big deal, but I thought I'd mention it anyway.
