Description

Both AMQP type double and float fail when run from QpidJms to QpidJms with the following error:

AssertionError: 
    sent:['0x00000000', '0x80000000', '0x40490fdb', '0xc02df854', '0x00000001', '0x80000001', '0x007fffff', '0x807fffff', '0x00800000', '0x80800000', '0x7f7fffff', '0xff7fffff', '0x7f800000', '0xff800000', '0x7fc00000', '0xffc00000']
received:['0x00000000', '0x80000000', '0x40490fdb', '0xc02df854', '0x00000001', '0x80000001', '0x007fffff', '0x807fffff', '0x00800000', '0x80800000', '0x7f7fffff', '0xff7fffff', '0x7f800000', '0xff800000', '0x7fc00000', '0x7fc00000']

(Similar for AMQP type double)

The underlying issue is that the IEEE encoding for -NaN is not supported in Java, or is not being correctly expressed. The test sends value 0xffc00000 (-NaN), but this is being returned as 0x7fc00000 (+NaN), causing the test to fail.

If this is in fact caused by Java's implementation of float and double, then this should not be considered a hard failure, but rather an expected failure which is ignored and does not cause the overall test to fail. Provision for this type of case should be made in the test framework.
