Comment (by strk):

 Reading the WKT from a file allows me to run the test, but the result of
 the test is a MULTILINESTRING EMPTY, dunno why:
 {{{
       FileInputStream fstream = new FileInputStream("/tmp/x");
       BufferedReader br = new BufferedReader(new
 InputStreamReader(fstream));
       String wkt1 = br.readLine();
       String wkt2 = br.readLine();
       String expected = "POINT EMPTY"; /* known to NOT be what we really
 want */
       double tol = 1.79499E-6;
       System.err.println("Using WKT1: " + wkt1);
       System.err.println("Using WKT2: " + wkt2);
       System.err.println("Using tolerance: " + tol);
       checkRounding(wkt1, wkt2, tol, expected);
 }}}

 Which results in:
 {{{
 FAIL - Expected = POINT EMPTY actual = MULTILINESTRING EMPTY
