string to double conversion results in questionable precision

      Description

      The following test:

      public void testString2Double_1() {
      try

      { Message message = senderSession.createMessage(); message.setStringProperty("pi", "3.14159"); assertEquals(3.14159, message.getDoubleProperty("pi"),0); }

      catch (JMSException e)

      { fail(e); }

      }

      Fails with:

      junit.framework.AssertionFailedError: expected:<3.14159> but
      was:<3.141590118408203>

      This appears to be because the client ends up doing the equivalent of
      Double.valueOf(Float.valueOf(value)) when doing string to double conversion
      rather than the more direct Double.valueOf(value).
