Environment

Inconsistency present on at least head and 9.0.5.0:

  • jruby 9.1.0.0-SNAPSHOT (2.3.0) 2016-05-02 1d36c5d OpenJDK 64-Bit Server VM 24.95-b01 on 1.7.0_95-b00 +jit [linux-x86_64]
  • jruby 9.0.5.0 (2.2.3) 2016-01-26 7bee00d OpenJDK 64-Bit Server VM 24.95-b01 on 1.7.0_95-b00 +jit [linux-amd64]

Linux Machine002 4.2.0-35-lowlatency #40-Ubuntu SMP PREEMPT Tue Mar 15 23:25:22 UTC 2016 x86_64 x86_64 x86_64 GNU/Linu

Expected Behavior

On MRI (2.3.1) I get Errno::ENOTDIR:

$ ruby -e 'Dir.entries("/etc/fstab")'
-e:1:in `open': Not a directory @ dir_initialize - /etc/fstab (Errno::ENOTDIR)
    from -e:1:in `entries'
    from -e:1:in `<main>'

Actual Behavior

On JRuby I get Errno::ENOENT

 ruby -e 'Dir.entries("/etc/fstab")'                                     
Errno::ENOENT: No such file or directory - No such directory: /etc/fstab
  entries at org/jruby/RubyDir.java:264
    <top> at -e:1

Is this issue still open, I would like to give it a shot. If I could get some directions.

@coders likely yes. check in RubyDir.java for a entries method implementation (annotated with @JRubyMethod)
