On Plan Summary Dashboard, Viewing "Show All Builds" Crashes For Large Number of Builds

I have a Bamboo plan that has 16158 build results. In the Plan Summary screen in the upper right there's a dropdown that says "Showing Last 25 Builds". If I change it to Show All Builds, Bamboo thinks for a while, then crashes with a stacktrace :

In my Bamboo I already have the JVM max heap up'ed to 6 GB and have tried passing -XX:-UseGCOverheadLimit to disable the GC overhead. However it still crashes when viewing all builds.
