Dir['{}'] crashes with java.lang.ArrayIndexOutOfBoundsException: 0

Trace: https://gist.github.com/mjc/24fa1402bf4571c7c8cb

Removing either spring or dotenv-rails makes it go away.

without trying it out ... do you happen to know if this was present in 1.7.19 ?

[mjc]

@kares yes, I discovered it in 1.7.19 initially.

can confirm it's a Dir[] thing when '{}' is passed ... work-around on its way
