--- Comment #1 from Harald Eilertsen <haraldei-freebsdbugz@anduin.net> ---
Did a quick scan through the OpenJDK sources, and found the following:
The most important use of /dev/fd is to be able to close any extra file
descriptors that for some reason don't have the O_CLOEXEC flag set when a new
process is forked.
/proc seems to be a bit more involved, and is used by the JVM for some memory
management, and determining system characteristics of certain architectures.
(PowerPC, s390, at least.) Not sure what impact it has to remove it, but the
effects may not immediately be obvious.
