I am using the JRI api to use “R” in Java. I have created a web-service which has the JRI code . When I consume this web-service for the first time it works properly, but with a subsequent request the JVM crashes and says : “The crash happened outside the Java Virtual Machine in native code.”

Is this somehow connected to the fact that R has no threading support, you can run only one instance of R within a multi-threaded application?
I am using Rengine to run R scripts in Java, I tried to stop/destroy the Rengine object but it did not work. How can I make sure that Rengine instance is garbage-collected before the second request.
Please let me know how can I solve this issue.
One can only create a single instance of Rengine using JRI. So use Rserve instead, which supports threading.
