Advantages of using JNA over native process execution

Question

I have a project that currently executes many native binaries using java.lang.Process. Assuming that their functionality is available in native library form - what would be the advantages of executing said library functions using JNA instead?

The process executions are fairly heavy - they take a few seconds to complete. Am I correct in thinking that performance gains would be minimal?

We went with native execution. As per the accepted answer, there is less risk of memory leaks and it's easy to restart the native process as needed.
