For historical reasons (well, I can see why they did it, but it's still
weird), array of box uses semicolon not comma as the delimiter between
array elements.

regression=# select '{"1.0,1.0,0.0,0.0","10.0,10.0,0.0,0.0"}'::box[];
ERROR: malformed array literal: "{"1.0,1.0,0.0,0.0","10.0,10.0,0.0,0.0"}"
LINE 1: select '{"1.0,1.0,0.0,0.0","10.0,10.0,0.0,0.0"}'::box[];
^
regression=# select '{"1.0,1.0,0.0,0.0";"10.0,10.0,0.0,0.0"}'::box[];
box
-----------------------------
{(1,1),(0,0);(10,10),(0,0)}
(1 row)

The advantage is you don't need double quotes:

regression=# select '{1.0,1.0,0.0,0.0;10.0,10.0,0.0,0.0}'::box[];
box
-----------------------------
{(1,1),(0,0);(10,10),(0,0)}
(1 row)

Whether this requires any special pushups on the JDBC side is beyond
my ken.
