Test Code:
System.setProperty("org.jruby.embed.localcontext.scope", "threadsafe");
System.setProperty("org.jruby.embed.localvariable.behavior",
"transient");
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine rbEngine = manager.getEngineByName("jruby");
ScriptContext context = new SimpleScriptContext();
String[] texts = new String[] {"ab", "cd"};
context.setAttribute("texts", texts, ScriptContext.ENGINE_SCOPE);
String rbScript =
" require 'java'\n" +
" puts 'test script'\n" +
" puts texts[0]\n";
rbEngine.eval(rbScript, context); // is OK
CompiledScript compiledScript = ((Compilable)
rbEngine).compile(rbScript);
compiledScript.eval(context); // throws exception
