While trying to port Facebook's Presto (https://prestodb.io/) to FreeBSD 10.2,
I got an Exception with the following stacktrace (running openjdk8-8.60.24_1):


javax.management.RuntimeErrorException: java.lang.InternalError: errno: 2

After investigating the code it seems like OpenJDK8 is using the wrong path to
check for open file descriptors on FreeBSD. Could this be an OpenJDK bug?
