Description

When using Groovy 2.3.3 under (Apple) JDK 6, the following warning is printed:

Jul 15, 2014 9:05:26 AM org.codehaus.groovy.runtime.m12n.MetaInfExtensionModule newModule
WARNING: Module [groovy-all] - Unable to load extension class [org.codehaus.groovy.runtime.NioGroovyMethods]

(No reason is given why the class cannot be loaded.) Attempts to use a method from NioGroovyMethods (e.g. Closeable#withCloseable) lead to groovy.lang.MissingMethodException.

Output of java -version:

java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)

PS: Groovy version 2.3.3 isn't available in JIRA (i.e. 2.3.3 isn't accepted for "Affects Version/s").
