Description

I'm seeing what seems to be a regression between Groovy-1.0-beta-3 and Groovy-1.0-beta-4-SNAPSHOT (built off the absolute latest CVS). I'm using a Groovy script to assemble a Picocontainer under the Nanocontainer servlet setup in web.xml ( See... http://docs.codehaus.org/display/NANO/NanoContainer+Servlet ). Configuring as described in that doc works fine under both beta3 and beta4-snapshot except when trying to do a System.out.println("I got here") debugging statement. With beta3, I see the debugging output just fine under Tomcat. With beta4-snapshot, I get the following exception which appears to be some classloading issue. Hopefully this will be enough info for the Groovy developers to determine the cause and fix the issue....
