> Checksum errors should always be reported first before doing any other checking on the
page.  Before this fix 
> the system would read in the page header first and as a side effect of the read do some
initial sanity checking which
> for some page corruptions would report errors and never get to the check sum check. 
Checksum errors should
> be reported first as they most quickly and clearly point to disk and system crash problems.
> For example in the database corruption reported in DERBY-4894  the following error was
reported when instead a 
> checksum error should have been reported:
> ERROR XSDB0: Unexpected exception on in-memory page Page(103,Container(0, 1137))
