>                 URL: https://issues.apache.org/jira/browse/QPID-2766
>             Project: Qpid
>          Issue Type: Bug
>          Components: Java Client
>    Affects Versions: 0.6
>            Reporter: Rajith Attapattu
>            Assignee: Rajith Attapattu
>            Priority: Minor

> 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).
