require fails after requiring rubygems in an embedded runtime in 1.9 mode
-------------------------------------------------------------------------
Key: JRUBY-5636
URL: http://jira.codehaus.org/browse/JRUBY-5636
Project: JRuby
Issue Type: Bug
Components: Embedding
Affects Versions: JRuby 1.6
Reporter: Tobias Crawley
Any require fails with a NPE after requiring rubygems in an embedded runtime in
1.9 mode. The following code recreates the issue:
{code}
import java.util.ArrayList;
import org.jruby.CompatVersion;
import org.jruby.Ruby;
import org.jruby.RubyInstanceConfig;
import org.jruby.javasupport.JavaEmbedUtils;
public class CreateRuntime {
public static void main(String[] args) throws Exception {
RubyInstanceConfig config = new RubyInstanceConfig();
//this works in 1.8
config.setCompatVersion( CompatVersion.RUBY1_9 );
//it fails with JIT on as well, just with a much uglier stack
config.setCompileMode( RubyInstanceConfig.CompileMode.OFF );
Ruby runtime = JavaEmbedUtils.initialize( new ArrayList<String>(),
config );
runtime.getLoadService().require( "rubygems" );
runtime.getLoadService().require( "date" ); //boom
//require via evalScriplet shows the same behavior
//runtime.evalScriptlet("require 'rubygems'");
//runtime.evalScriptlet("require 'date'");
}
}
{code}
The stack:

This was with jruby-complete-1.6.0.jar from maven. I compiled and ran it with:
{noformat}
$ javac -cp
/Users/tobias/.m2/repository/org/jruby/jruby-complete/1.6.0/jruby-complete-1.6.0.jar
CreateRuntime.java
$ java -cp
/Users/tobias/.m2/repository/org/jruby/jruby-complete/1.6.0/jruby-complete-1.6.0.jar:.
