> Recent trunk changes now produce more assertive warnings about use of deprecated configuration properties. With some of these deprecated properties included in core-default.xml, that means every process launched logs the warnings. Remove them from core-default.xml to avoid these warnings. (Note that this does not take the step of actually removing the code that uses the deprecated properties. They'll continue to work. We just don't want warnings logged by default if the user didn't specifically use these properties.)
