Java 在第一次应用程序启动期间获取“ERROR DefaultExtensionsRegistry-为字体实例化扩展注册表时出错”

我使用的是JasperReports 3.7.2、iReport 3.7.2和JRE 1.6.0.20

首先，当我将报告生成为PDF时，我得到了以下错误报告，但该报告已正确生成：

子Qent尝试生成PDF是成功的，没有错误。 仅在运行应用程序后第一次生成PDF时出错

错误与操作系统无关，它发生在Windows以及UNIX AIX和Linux上

请有人给我一些线索来解决这个问题。

您的jar文件中似乎有一种字体无法解析。我知道你永远不会读到这条评论，但它似乎是显而易见的。它只是跳过该字体，之后就不再尝试读取字体扩展名
