Environment methods may not use actual current environment

[mvz]

Summary

Something weird is going on here: #603 (comment)

Expected Behavior

#cd and other methods that start an environment block should start from the actual current environment at that point. It seems #cd is not doing so in the build linked above, since there is code in Aruba that sets the JRUBY_OPTS env var and it looks like that set value is ignored.

Possible Solution

None, more investigation is needed.

[mvz]

I'm going to close this for now since the specs explicitely test using the current ENV. The build failure was fixed anyway.
