Steven Hawkins resolved TEIID-4403.
-----------------------------------
Resolution: Done
Expanded/corrected sizeutility logic and will allow arrays of up to an 8MB estimated memory footprint.
Next steps from here include allowing for a serialized form, which may require extensive changes to ArrayImpl, and the ability for odata or other paths to set a session variable or other mechanism to temporary up the limit.
