Hi there!
I'm new to jminer and currently i'm like to test the poc1 / poc2 feature.
I created 3 testplotfiles (each 100GB / poc1), and 1 testplotfile (100GB / poc2), stored in different directories (c:\burst\plots\poc1 and c:\burst\plots\poc2).
Actually i tried to start jminer just with plotPaths=C:/burst/plots/poc1 configured.
Configfile looks good to me but jminer throws an exception:

I attached also my jminer.properties
jminer-properties.zip

All is done on a:
intel i7-4790K, Nvidia GTX970, 16GB RAM, Win10pro 64bit

Confirmed from my side that it's working now! May my tests begin ;)

This shouldn't be distressing! When someone is working there are always mistakes!
Thanks you VERY MUCH for this fast fix and your work in general!
