[pde-dev] excessively long startup with p2 update-based target platform

[Vincent Smith <vinceos@xxxxxxxxxxx>]

I just upgraded my version of Eclipse to 4.5.1. I have a target platform that uses p2 update sites exclusively and if I make it active, it takes 1 min 20 seconds for the instance of Eclipse to startup. If I use the running platform instead, it takes all of 10 seconds.

I found a bug report (https://bugs.eclipse.org/bugs/show_bug.cgi?id=446845) which seems to suggest that the issue crept in between 4.5M1 and 4.5M2, but apparently has been fixed in the latest version of Mars. In light of my unsuccessful attempt, what specific version of Mars eliminates this issue if I use a target platform with p2 update sites?
