我正在使用JasperReports 3.7.2、iReport 3.7.2和JRE 1.6.0.20。

首先，当我生成PDF报告时，出现以下错误（但报告已正确生成）：

2012-08-24 10:03:49,302 [http-8180-1] ERROR DefaultExtensionsRegistry - Error instantiating extensions registry for fonts

生成PDF的后续尝试成功且没有错误。错误仅在运行应用程序后第一次生成PDF时发生。

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

请有人给我线索来解决这个错误。

似乎您的 jar 文件中的一种字体不可解析。我知道您永远不会阅读此评论，但这似乎很明显。它只是跳过该字体，之后不再尝试读取字体扩展名。
