Hi devs, I see that Denis has added the following: if ("1".equals(config.getProperty("xwiki.store.migration.exitAfterEnd", "0"))) { logger.error("Exiting because xwiki.store.migration.exitAfterEnd is set"); System.exit(0); This is really bad IMO since System.exit should never be used in JavaEE/Servlet apps. See also http://nemo.sonarsource.org/drilldown/violations/XWIKI?rids%5B%5D=367322&rul... One problem for example is that this will stop the full Servlet JVM so if XWiki runs in a Servlet container running several other webapps suddenly the whole Servlet container will go down! What should be done instead is to remove this "feature" which has no real meaning in a Servlet environment. I'm thus proposing to deprecate this feature. I don't even understand what use cases it brings. WDYT? Thanks -Vincent
