Quincy Qu updated WW-4999:
--------------------------
    Description: 
I'm in devMode, enabled logMissingProperties and expect to see missing property 
warning in the log. I was surprised that I can't get the missing property log 
even if logMissingProperties is set true. The application run smoothly and skip 
the missing property - as expected though.

In another run, I enabled both logMissingProperties and 
throwExceptionOnFailure. This time the application crash at the missing 
property and I can get both logs and exception.

After I dive deeper using debugger, I convince myself the config is good, since 
devMode and logMissingProperties are true at runtime in OgnlValueStack.

I was confused, why we can't get missing property log without throwing 
OgnlException? 

Are we able to enter handleOgnlException(String expr, boolean 
throwExceptionOnFailure, OgnlException e)  at all if throwExceptionOnFailure is 
false, in which my expected log is written?
