Issue1535

While processing scripts, Jython does not take into account the bindings it gets through PyScriptEngine.eval() method:

import org.junit.Test;

import javax.script.Bindings;
import javax.script.ScriptContext;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.SimpleBindings;

public class TestJSR223BindingsWithJython {

  @Test public void should_set_bindings_to_engine_scope() throws Exception {
    final ScriptEngineManager manager = new ScriptEngineManager();
    final ScriptEngine engine = manager.getEngineByName("jython");

    final Bindings bindings = new SimpleBindings();
    bindings.put("name", "Tiago");

    engine.setBindings(bindings, ScriptContext.ENGINE_SCOPE);
    engine.eval("print \"Hello, \" + name + \"!\"");
  }

  @Test public void should_override_engine_scopes_bindings() throws Exception {
    final ScriptEngineManager manager = new ScriptEngineManager();
    final ScriptEngine engine = manager.getEngineByName("jython");

    final Bindings bindings = new SimpleBindings();
    bindings.put("name", "Tiago");

    engine.eval("print \"Hello, \" + name + \"!\"", bindings);
    
    /*
    javax.script.ScriptException: NameError: name 'name' is not defined in <script> at line number 1

    */
  }
}

Maybe it's related to #1426.

This should be fixed in Jython trunk. Please let me know if it isn't.
