You're only seeing inconsistencies because you're using unquoted
identifiers on the SQL side. Java strings are case-sensitive; the
behaviour of getTables is consistent with what you get when using
case-sensitive (i.e. quoted) SQL identifiers. Witness:

$ psql testdb
Welcome to psql 7.4.1, the PostgreSQL interactive terminal.
[...]
testdb=> create table "test" (k int4);
CREATE TABLE
testdb=> create table "Test" (q int4);
CREATE TABLE
testdb=> \d "test"
      Table "public.test"
  Column |  Type   | Modifiers
--------+---------+-----------
  k      | integer |

testdb=> \d "Test"
      Table "public.Test"
  Column |  Type   | Modifiers
--------+---------+-----------
  q      | integer |
