[Neo] IllegalStateException meaning

I think it would be valuable to understand why the memory requirements are
so large and how best to manage these types of situations in addition to
increasing the heap, since it seems that in some cases this merely delays
the issue. Is there any internal instrumentation on Neo memory usage that
could be used to help tune/tweak the settings? If not, would it make sense
to add a couple of MBeans for this type of information?

I just got this same problem, and was able to defeat by upping heap
size. It was very strange - does Transaction#finish do some
