JRuby raises IOError instead of specific error if File.rename(a,b) fails due to hidden filesystem #5318
Description
Environment
jruby -v
jruby 9.2.0.0 (2.5.0) 2018-05-24 81156a8 OpenJDK 64-Bit Server VM 25.172-b11 on 1.8.0_172-b11 +jit [freebsd-x86_64]
FreeBSD jrails5.zuhause.org 11.1-RELEASE-p9 FreeBSD 11.1-RELEASE-p9 #0: Tue Apr 3 16:59:16 UTC 2018 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64
This is running in a FreeBSD jail where /tmp is a tmpfs file system, current path is in /home, which is under the root filesystem, and enforce.statfs=2 flag is set for the jail, so Files.getFileStore fails with Mount point not found in fstab if one or both paths are within /tmp. This difference causes bundler to fail.
