Most likely yes. See bug comments for more details.A) why are xstram and joda.time now required ? were they accidentally removed in the "great TP reduction refactor" ? If yes - great, this is a fix for that.
JBIDE-16910 isn't about installation time, otherwise install-grinder would have caught it. It's only an issue when trying to install everything from target-platform directly in your IDE, which is not a user scenario we test.btw. is the atlassian issue fixed in Beta1 or just Beta2 ? according to JBDS-3000 at least snjezana does not see the missing xstream.
