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。
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Jasper的多线程有关（ThreadLocal-stuff）。
我们尝试过java.awt.headless = true JVM设置，正如一些建议所示，但没有任何变化。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...... 我们如何解决此类问题？
Jasper Reports 4.7（也与3.7一起发布）
Java 1.6，Flex（服务器上的GraniteDS）/ Spring / Hibernate
（我们不使用EJB，我们通过一个简单的war文件进行部署）
