创建JAXBContext.newInstance报NullPointerException

Question

Jdk 1.6.0 跑的一个多线程本地应用服务，基于AIX平台，运行好几年了， 今年（2016）报错2次创建对象失败的问题。
项目的基本情况是使用jaxb解析和组装xml格式的报文，每个线程每次独立完成一个报文的解析或组装，发生问题的过程是在组装过程，2次出错都是组装同一类报文。
以下是错误日志，跟了整个过程的源代码，没有发现可疑点，放出来碰碰运行，是否有遇到类似问题的朋友：

Answer 1

调用的代码， 传入的参数都是自动生成的类
public JaxbBinder(Class<?>... types) {
try {
jaxbContext = JAXBContext.newInstance(types);
} catch (JAXBException e) {
throw new RuntimeException(e);
}
}
