Lukasz Lenart commented on WW-4348:
-----------------------------------
Nope, by defining
{code:xml}
<constant name="struts.ognl.allowStaticMethodAccess" value="true" />
{code}
you'll enable access to static methods, setting {{false}} it'll be disabled.
But access to static methods was very often use as a hacker's attack vector on
users' applications. See PoC here http://struts.apache.org/docs/s2-009.html
