JRuby10: (NameError) undefined local variable or method 'it' in eval #8735
Description
After #8723 was fixed, I came across a new problem with it, but this time:
- it works fine on jruby cli built using rbenv
- The problem only exists in JRubyEngine interpreted code
I have reused https://github.com/jimtng/jruby10-bundle to demonstrate the problem, but in summary:
code:
package com.example;
import javax.script.ScriptEngine;
public class App {
public static void main(String[] args) throws Exception {
javax.script.ScriptEngineFactory factory = new org.jruby.embed.jsr223.JRubyEngineFactory();
ScriptEngine engine = factory.getScriptEngine();
engine.eval("""
puts "JRuby Version: #{JRUBY_VERSION}"
puts "JRuby Revision: #{JRUBY_REVISION}"
[1, 2].each do
puts it
end
""");
}
}Output:
