Thanks for all the replies and suggestions here. A few answers to
questions:
1. Is this a 32-bit or 64-bit JVM?
Its 64-bit, confirmed.
2. what type of geometry is this? and how many vertices does it have?
It has 70232 vertices and the file containing the WKT data is 127 MB in size
3. Am I sure its not a data issue? Not at this point. I will take
Imran's suggestion and see if I can implement the JTS test suite.
