Support for this property was removed as of Wrapper version 3.3.6 because of a number of problems with the values being sticky after JVM restarts and configuration reloads.

In almost all cases, this property is no longer needed because the Event Handler Variables are inserted into the property values at the time that event properties are referenced.

The only problem with removing support for this property is that the child processes can no longer reference the Event Handler Variables as environment variables. This can be worked around in most cases by passing parameters to the child process.
