It looks like the 'if' statement (and 'for') can't be split across
'exec' statments.

Neither this:

   python.exec("if 1:");
   python.exec("  print 'true'");

nor this:

   python.exec("for x in range(1,2):");
   python.exec("  print x");

work for me. Of course this works:

    python.exec("for x in range(1,2): print x");

or this (multiple lines in a SINGLE 'exec':

    String s = "if 1: \n print 'true'";
    python.exec(s);
