Subject [jira] [Created] (WW-4999) Can't get OgnlValueStack log even if enable logMissingProperties

-----------------------------

             Summary: Can't get OgnlValueStack log even if enable logMissingProperties
                 Key: WW-4999
                 URL: https://issues.apache.org/jira/browse/WW-4999
             Project: Struts 2
          Issue Type: Bug
          Components: Value Stack
    Affects Versions: 2.5.17
            Reporter: Quincy Qu
             Fix For: 2.5.17


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, Object value, boolean throwExceptionOnFailure,
OgnlException e)

at all if throwExceptionOnFailure is false, in which my expected log is written?
