[1.9] splat with nil produces incompatible with MRI results
-----------------------------------------------------------
Key: JRUBY-4584
URL: http://jira.codehaus.org/browse/JRUBY-4584
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules, Ruby 1.9
Affects Versions: JRuby 1.4
Environment: Latest jruby
Reporter: Vladimir Sizikov
Consider the following:
{code}
p [*nil]
p [1, *nil]
{code}
MRI 1.9.2 will print:
{noformat}
ruby 1.9.2dev (2010-02-10 trunk 26632) [i386-mingw32]
[]
[1]
{noformat}
JRuby in 1.9 mode will print:
{noformat}
jruby 1.5.0.dev (ruby 1.9.2dev trunk 24787) (2010-02-23 2a8097f) (Java
HotSpot(TM) Client VM 1.6.0_18) [x86-java]
[]
[1, nil]
{noformat}
This will lead to the following funny script (tribute to why):
http://gist.github.com/311762 to produce different results under JRuby,
compared to MRI 1.9.
