我正在努力处理一些代码，这些代码在 jenkins 上系统性地失败，但当然在我的机器上没有问题地通过了。
public static FaultException getFaultException(String faultCode, String faultString) {
LOGGER.debug("start getFaultException");
Fault fault = new Fault();
fault.setFaultCode(faultCode);
fault.setFaultString(faultString);
LOGGER.debug("Returning new FaultException");
FaultException fex = new FaultException("Fault exception", fault);
LOGGER.debug("fex is ", fex);
try {
if (fex == null) {
LOGGER.debug("getFaultException fex is null");
}
}catch(NullPointerException nex) {
LOGGER.debug("catched npe ", nex);
}
LOGGER.debug("fex class is " + fex.getClass().getCanonicalName());
LOGGER.debug("fex built in getFaultException");
return fex;
}
你看到的代码会在jenkins catched npe + the null pointer exception上显示，并且会在下一行重新触发一个npe。所以基本上我在检查对象是否为 null 时有一个 npe(if (fex == null) 行是罪魁祸首)。然而 LOGGER.debug("fex is ", fex);行将成功转储 FaultException 对象。
这怎么可能？jenkinks机器运行openjdk 1.7.0_85-b01，我的机器是1.7.0_80的windows机器。此外，FaultException 类是生成的类，带有 @WebFault 注释，但我比较了两台机器上的结果字节码并且是相同的。 (路径之类的除外)
感谢您的关注!
