can definitely appreciate the intent of this patch but I suspect we'll need
to handle this differently. Once an OOME has happened the JVM might still
function well but things can be unpredictable/unreliable. Rather than catching
such a thing and warning the user we should instead prevent data of a certain
size from being retrieved via this mechanism.
