An ArrayList is not an array -- it is a List implementation which
uses an array, internally.  What happens if you use the toArray
method to extract an array from the List and pass that in?

OK, that looks like an array, so I'm now a bit lost.

Could you put together a self-contained example of how to create the
problem?  (Self-contained meaning that I can take what you provide
and run it, without writing any Java or plpgsql code or inventing
table or type definitions -- which might or might not match what you
did well enough to show the problem.)  It's most helpful if you keep
removing things until you have the *smallest* example which still
shows the problem.
