Myrna van Lunteren resolved DERBY-6504.
---------------------------------------

       Resolution: Fixed
    Fix Version/s: 10.10.2.1
                   10.11.0.0

I do not intend to backport this further, though I see no reason why it couldn't be - except it adds a new message, which we typically do not backport.

> Users have reported databases that will not boot with stack traces showing:
> Caused by: java.lang.ArrayIndexOutOfBoundsException
> at java.lang.System.arraycopy(Native Method)
> at org.apache.derby.impl.store.raw.data.AllocPage.ReadContainerInfo(Unknown Source)
> at org.apache.derby.impl.store.raw.data.FileContainer.readHeader(Unknown Source)
> I suggest the code be changed to catch the out of bounds and turn it
> into a StandardException and include as much runtime information as
> possible so that the underlying problem can be diagnosed.  Information
> should include sizes of both arrays, the amount of data being copied ("N"),
> and possibly a hex dump of the source array.
