Re: [equinox-dev] Parallel bundle activation?

[Lars Vogel <lars.vogel@xxxxxxxxxxx>]

Thanks everyone for the prompt reply.

@Tom, I agree unfortunately the Eclipse IDE has multiple long running
activators, e.g., JDT UI takes 1/2 a second and these startups add up.
The SDK starts for example for me in approx. 8 seconds while an EPP
may need > 20 seconds. And fixing all of the IDE contributions is not
realistic.

In implies some kind of design flaw because you must have some long running BundleActivators if you want to run them in parallel.  You are better off investigating why you must have long running BundleActivators.
