Re: [Wrapper-user] wrapper.filter.trigger property question ...

[Richard E. <rem...@ed...>]

We've used this feature for years. It very, very important
that the folks writing messages that will appear in the
log file output do not inadvertently have a string that
will match one of the trigger strings. As an example,
our trigger string at one time was "Error". Well some
well meaning programmer produced a log message that included
that string (when an obscure branch of code executed).
Bang, the application was shutdown and restarted.
So, now all of our trigger strings are the full
class names of the java.lang.Error exceptions types, such as
"UnsupportedClassVersionError".
