Howard Gao 90ca87c5e1 ARTEMIS-2088 - Page.write() should throw exception if file is closed
In Page.write(final PagedMessage message) if the page file is closed
it returns silently. The caller has no way to know that if the message
is paged to file or not. It should throw an exception so that the
caller can handle it correctly.

This causes random failure PagingTest#testExpireLargeMessageOnPaging().
The test shows that when the server stops it closes the page file.
In the mean time a message is expired to the expiry queue and if
the expiry queue is in paging mode, it goes to Page.write() and
returns without any error. The result is that the message is removed
from the original queue and not added to the expiry queue.

If we throw exception here it makes the expiration failed, the message
will not be removed from the orginal queue. Next time broker is started,
the message will be reloaded and expired again. no message lost.
