Supplier type parameter function can import to ParserContext, But expression complile fail and can not use it?

[linux2014linux]

I add success custom method to ParserContext. But It complie fail it when I use expression.

public class LogicFunction {
  public static Object IFERROR(Supplier<Object> expression, Object defaultValue) {
      try {
          return expression.get();
      } catch (Throwable e) {
          return defaultValue;
      }
  }
}

public class MvelTest {
  @Test
  public void test() {
    ParserContext context = new ParserContext();
    Method[] declaredMethods = LogicFunction.class.getDeclaredMethods();
    for (Method declaredMethod : declaredMethods) {
        context.addImport(declaredMethod.getName(), declaredMethod);
    }

    Map<String, Object> data = new HashMap();
    Serializable serializable = MVEL.compileExpression("IFERROR(() -> 1/0, -1)", context);
    Object fieldValue = MVEL.executeExpression(serializable, data);
    System.out.println(fieldValue);
  }
}

Follow error information.

[Error: Malformed expression]
[Near : {... IFERROR(() -> 1/0, -1) ....}]

Anyone help me? Thank you!
