Environment

Flags

-J-Dfile.encoding=UTF-8

The problem is with parsing this flag.

Versions affected

  • jruby 9.2.0.0 (2.5.0) 2018-05-24 81156a8 OpenJDK 64-Bit Server VM 10.0.1+10-Ubuntu-3ubuntu1 on 10.0.1+10-Ubuntu-3ubuntu1 +jit [linux-x86_64]
  • jruby 9.1.17.0 (2.3.3) 2018-04-20 d8b1ff9 OpenJDK 64-Bit Server VM 10.0.1+10-Ubuntu-3ubuntu1 on 10.0.1+10-Ubuntu-3ubuntu1 +jit [linux-x86_64]
  • jruby 9.1.17.0 (2.3.3) 2018-04-20 d8b1ff9 Java HotSpot(TM) 64-Bit Server VM 10.0.2+13 on 10.0.2+13 +jit [darwin-x86_64]

Presumably this affects 9.1.17.0 and 9.2.0.0 on all platforms that use the bash start script.

Platforms affected

Linux – for demonstration, I tested in the plain ubuntu Docker container, just installing openjdk-11-jdk and curl and then downloading the dist tarballs: Linux df62e87ad0af 4.9.93-boot2docker #1 SMP Thu May 10 16:27:54 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
Darwin: Darwin mr-2.local 16.7.0 Darwin Kernel Version 16.7.0: Thu Jun 21 20:07:39 PDT 2018; root:xnu-3789.73.14~1/RELEASE_X86_64 x86_64

Installed or activated gems

none

Application/framework version (e.g. Rails, Sinatra)

none

Environment variables

none specifically, locale in the container is POSIX, on Darwin en_US.UTF-8.

Expected Behavior

JRuby honors the file.encoding set on the command line, as 9.1.16.0 does.

Actual Behavior

I believe this is a regression, introduced in fda229c.
