Whew! Thank goodness it is x86_64. You had me very worried when you said
this was i386 :-)

So, this is indeed a problem with the test. The internal detail message
for the IOException will vary according to the Linux kernel release. If
MAP_SYNC is not supported by the Linux kernel it will embed the message
you saw. If it is supported the message will be the one the test checks for.

I think the best thing is for the test not to bother checking for a
specific message. The important thing is that we should get either
IOException or UnsupportedOperationException. Checking for the message
is not really necessary. I will remove this check from the test.
