Review accidental xml config changes

[janbartel]

jetty-10/jetty-11

This supersedes issue #6329. Analysing #6329 (jetty 10/11 does not stop on shutdown by default when running in the distro) revealed that commit 343cf73 had inadvertently changed a number of default values in jetty xml config files. We need to review the config changes, and where necessary revert/fix incorrect changes.
