Try creating the List as an ArrayList and copying the elements into it
using a loop. I assume this will work as you say you are not having
problems with other List types.
Also does a #foreach using the List created by Arrays.asList work? I am
using this function and have not noticed a problem, but off the top of
my head i do not know that i ever call size() from a template on the
resulting list.
If the problem appears to be in the object created by Arrays.asList, I
would mention it on the velocity list. Not sure whether this would be a
problem with velocity, but it could save some other users the trouble of
getting the same error.
