$ jruby -ve "File.open('foo.test', 'wb').pos"
jruby 9.0.0.0 (2.2.2) 2015-07-21 e10ec96 OpenJDK Server VM 24.80-b11 on 1.7.0_80-b15 +jit [OpenBSD-i386]

This only happens on OpenBSD-i386, it does not happen on OpenBSD-amd64. I've also tried using JDK 1.8.0, but receive the same error with that, here's the jruby -v line for that:

jruby 9.0.0.0 (2.2.2) 2015-07-21 e10ec96 OpenJDK Server VM 25.45-b02 on 1.8.0_45-b14 +jit [OpenBSD-i386]

Any ideas where to look for the fix? Is this something that could be fixed in jnr-posix?
