Description

The following expression evaluates properly in OGNL 2.6 and outputs "1":

<span jwcid="@Insert" value="ognl:true ? 1 : 1/0" />

In OGNL 2.7 it evaluates the 1/0 and you get the error page with a divide by zero error. The unused expression should not be evaluated because it may not be valid (in more useful ways than this contrived example).
