I am not to sure about Blackdown but I do that I IBM JVM for Linux.
(1.1.7 is going to be available very soon, with 1.2 to follow close) has
unbeleivable garbage collection. They do the GCing similar to HotSpot
actually if I am not mistaken their GCing is better than HotSpot.
So you even if it is not provided by Blackdown you will have an alternative.
