A DESCRIPTION OF THE REQUEST :
This method eases the recalculation of insufficient array size.
Some VMs reserve some header words in an array.
Attempts to allocate larger arrays may result in OutOfMemoryError: Requested array size exceeds VM limit
java.lang.System seems to be an appropriate home.


JUSTIFICATION :
Increasing an array is a common task in the JDK.
Exemplary use case: see bug 7153238
