One of our customers is calling JTS libraries out of a Hive UDF and noticed
a pretty dramatic jump of heap memory usage between JDK 1.6 and JDK 1.7.
We bumped up heap and added some CMS GC options to help, but were curious
if anyone else had experienced any problems.
I noticed 1.13 is out, does that help with heap usage?
