Looking at the original JIRA issue (MATH-1130) it was not clear that this is actually related to MATH-1120 and sounded like a user request to support this functionality. As this functionality is used by Commons Math itself the inclusion is of course ok. Regarding the supported versions: * for the 3.x branch I would stick with java 5 * for the new 4.x branch I would at least switch to java 7 Thomas --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
