* Fix for NPE issue discovered in WW-5004 (amended commit).
- Guard fix for a NPE that can arise under certain conditions, identified by A.
Mashchenko.
- Requires the following elements to implement a fuller fix:
- Back-port relevant guard logic in ProxyUtil from master into 2.5.x to deal
with the NPE.
- Update SecurityMemberAccess to block access to static fields.
- Upgrade to OGNL 3.1.22 (re-enables access to public static fields w/out
access checks).
- Add unit test to confirm proper functionality of the fix.
- Correct missing entry in 4 test configuration XML files (needed for new
unit test).
- Replaced literal injection parameter name for setStaticFieldAccessLevel in
OgnlValueStackFactory with the appropriate constant.
Note: Even though a constant was defined in StrutsConstants, the value for
the injection name in all places is the XWorkConstants.
It has to remain the same to avoid breaking anything.
