Description

println ([1]+[2]) produces [1, [2]], not [1, 2]. This is true for longer lists, and lists of other things.

Setting breakpoints in DefaultGroovyMethods.plus, both the (Colleciton, Collection) and (Collection, Object) version, revales that MetaMethod.inkvoke() calls:

reflector.invoke(this, object, arguments);

where object = null and arguments is an Object[] with the two ArrayLists. But for some mysterious reason, Collection_GroovyReflector.invoke() calls plus(Collection, Object) rather than plus(Collection, Collection).

This is the end of my foo, I don't know how to figure out what's going on inside the reflector.

This is in Java 1.5.0_03, if that makes a difference.
