JRuby 1.7: Argument list not fully preserved when inproc=true

[olleolleolle]

Environment

• JRuby version 1.7.26 with JRUBY_OPTS="-J-Djruby.launch.inproc=true"
• OS X, Linux

• use jruby-1.7.26
• with in a inproc=true
• call a subshell with system(cmd_string_here)
• and have it take a --pattern arg with a glob-expanding argument, like *.exe
• That last argument will be eaten

Background & observations:

• Using rspec's Rake task to have a subshell open gives this stacktrace
• This has no problems in 9.1.6.0

Two small programs collaborate to show output

#!/usr/bin/env ruby
#
# sys.rb
#
puts "SYS"
p ARGV

#
cmd='ruby reader.rb --pattern \*.rb' # ["--pattern", "*.rb"]
cmd='ruby reader.rb --pattern *.rb' # ["--pattern", "reader.rb", "sys.rb"]
cmd='ruby reader.rb --pattern {.rb' # ["--pattern"]
cmd='ruby reader.rb --pattern spec/\*\*\{,/\*/\*\*\}/\*_spec.rb' # ["--pattern"]

cmd='ruby reader.rb --pattern /\*.rb' # ["--pattern"] <- enebo's minimization

system(cmd)

and reader.rb:

#!/usr/bin/env ruby
puts 'READER'
p ARGV

Expected:

JRUBY_OPTS="-J-Djruby.launch.inproc=false" ruby sys.rb
SYS
[]
READER
["--pattern", "spec/**/*_spec.rb", "spec/**/*/**/*_spec.rb"]

Actual

RUBY_OPTS="-J-Djruby.launch.inproc=true" ruby sys.rb
SYS
[]
READER
["--pattern"]

I suspect that 9k is not actually observing the inproc flag, which is probably why it's working there.

I would also be surprised if this is a recent regression.

1.7.x will be EOL after 1.7.28 and no one has stepped up to solve this.
