Description Tobias Feldhaus 2015-12-10 13:54:21 UTC

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 error: Unable to open directory /proc/self/fd

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?

This problem seems to be introduced in r372338, i.e., mis-merged fix for JDK-8031581:
