Genson的内部库代码导致了一个ArrayIndexOutOfBoundsException，因为它试图索引数组，我认为数组是空的。见下文。

我得到以下堆栈跟踪：

        at com.owlike.genson.ext.jaxrs.GensonJsonConverter.writeTo(GensonJsonConverter.java:85)

这是由Genson库中的以下方法造成的：

  public PropertyMutator createMutator(String name, Method method, Type ofType, Genson genson) {
      Type expandedType = TypeUtil.expandType(method.getGenericParameterTypes()[0], ofType);
      return new PropertyMutator.MethodMutator(name, method, expandedType,
        getRawClass(ofType));
    }

它来自方法中的以下代码：method.getGenericParameterTypes().当我调试时，它说方法是“错误”。它试图对MyObject具有以下方法的列表进行操作(只显示失败的方法)：

@XmlElement(nillable=true)
    public String getError() {
        return error;
    }
    public void setError(String error) {
        this.error = error;
    }

我该怎么对付这个虫子？干吗干吗这么做？

这确实是一个错误，并且已经在此承诺中修复了。修复将是第1.5版的一部分。
