Command line arguments ignored when RUBYOPT is set
--------------------------------------------------
Key: JRUBY-3962
URL: http://jira.codehaus.org/browse/JRUBY-3962
Project: JRuby
Issue Type: Bug
Components: Miscellaneous
Affects Versions: JRuby 1.4
Environment: Linux
Reporter: Choi, Junegunn
Priority: Minor
When RUBYOPT environment variable is set, command line arguments are ignored as
follows.
> export RUBYOPT=rubygems
> jruby -e 'p ARGV' a b c
[]
> unset RUBYOPT
> jruby -e 'p ARGV' a b c
["a", "b", "c"]
This seems like a bug to me. I looked into the code and found that
ArgumentProcessor.processArguments is called twice when "RUBYOPT" is set,
and it does not preserve the arguments previously processed by the first call.
A simple patch.
