Description

TestCheckpoint#testSecondaryHasVeryOutOfDateImage occasionally fails due to unexpected exit, due to an NPE while checkpointing. It looks like the background checkpoint fails, conflicts with the explicit checkpoints done by the tests (note the backtrace is not for the doCheckpoint calls in the tests.
