Jasper Reports + WebSphere 7，ExceptionInInitializerError异常 [英] Jasper Reports + WebSphere 7, ExceptionInInitializerError exception

问题描述

调用JasperFillManager.fillReport（）时，我们得到以下异常。令人困惑的是，它发生在我们的生产环境中，但在我们的测试环境中工作正常。

We're getting the below exception when calling JasperFillManager.fillReport(). The confusing aspect is that it happens in our "production" environment, but works fine in our TEST environment.

显然这个问题发生在静态属性的初始化过程中，我们认为它可能与多线程Jasper有关（ThreadLocal-stuff）。

Apparently this issue happens during initialization of a static property, and we think it may be related to the multi-threading Jasper does (ThreadLocal-stuff).

我们尝试了java.awt.headless = true J​​VM设置作为一些建议已经表示，但没有变化。我们真的需要有关故障排除的建议，或者在一个环境中可能导致这种情况的线索，而不是另一个环境中的原因。据我们所知，它们是相同的，但显然某些东西是不同的，我们没有想要检查的东西。
所以问题确实是......
我们如何解决这样的问题呢？

We've tried the java.awt.headless=true JVM setting as some suggestions have indicated, but there was no change. We're really in need of suggestions for troubleshooting, or clues as to what might cause this in one environment but not the other. As far as we can tell, they're the same, but obviously something is different and we're out of ideas for things to check. So the question really is... how can we troubleshoot an issue like this?

推荐答案

要解决问题，您需要获取由此引发的原始异常静态初始化器。通常，该异常链接到ExceptionInInitializerError，这是第一次尝试加载包含静态初始值设定项的类。

To troubleshoot the issue, you need to get the original exception thrown by the static initializer. Normally that exception is linked to the ExceptionInInitializerError, the first time an attempt is made to load the class that contains the static initializer.

因此，您需要做两件事：

Therefore you need to do two things:

1. 确保您能够获得整个堆栈跟踪。您发布的堆栈跟踪似乎被截断（请参阅 *** BUFFER OVERFLOW *** 标记）。


2. 获取在第一次初始化类的尝试时抛出异常的堆栈跟踪。如有必要，请重新启动应用程序或服务器。

1. Ensure that you are able to get the entire stack trace. The stack trace you have posted seems to be truncated (see the ***BUFFER OVERFLOW*** marker).
2. Get the stack trace of the exception thrown when the first attempt to initialize the class is made. If necessary, restart the application or server.
