URL: http://jira.codehaus.org/browse/JRUBY-4887
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.5.1
Environment: % java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)

The latest git version (1f0e0d1f7dc09580d1d287799997a437a34f5684),
Jruby don't work with EUC-JP Linux locale. See below:
% LANG=ja_JP.utf8 jirb
irb(main):001:0>
% LANG=ja_JP.eucJP jirb
OSEnvironment.java:81:in `getAsMapOfRubyStrings': java.lang.NullPointerException
from OSEnvironment.java:60:in `getEnvironmentVariableMap'
from RubyGlobal.java:300:in `defineGlobalEnvConstants'
from RubyGlobal.java:277:in `createGlobals'
from Ruby.java:1080:in `init'
from Ruby.java:173:in `newInstance'
from Main.java:217:in `run'
from Main.java:128:in `run'
from Main.java:97:in `main'
I found that problem caused by getAsMapOfRubyStrings() method in
OSEnvironment.java.
Map envs = new HashMap();
Encoding encoding =
EncodingDB.getEncodings().get(Charset.defaultCharset().name().getBytes()).getEncoding();
...
[debug]
0. LANG=ja_JP.eucJP
1. Charset.defaultCharset().name() => "x-euc-jp-linux".(#1)
2. EncodingDB.getEncodings().get("x-euc-jp-linux") => null
3. NullPointerException :-(
