JRuby + minitest failing because of ObjectSpace

I am new to JRuby, and I'm trying to get my test suite running correctly. I'm using minitest, and it looks like minitest requires the ObjectSpace to be enabled. I've tried each of the following commands:

bundle exec jruby -X+O -S rake
jruby -X+O -S bundle exec rake
JRUBY_OPTS="-X+O" bundle exec rake
export JRUBY_OPTS="-X+O" && bundle exec rake

and all of them result in the following stack trace:

RuntimeError: ObjectSpace is disabled; each_object will only work with Class, pass -X+O to enable
each_object at org/jruby/RubyObjectSpace.java:167

Any ideas what the proper command is to re-enable the ObjectSpace when running rake? I have run commands like

bundle exec jruby -X+O test/functional/my_test.rb
bundle exec jruby -X+O -S irb

with no issues, so it seems somehow related to rake specifically.

Does your rake task spawn subprocesses? If so, JRuby might be reusing the current JVM process. Try exporting JRUBY_OPTS='-X+O -J-Djruby.launch.inproc=false'.
