我一直有一个奇怪的问题，我无法解决。每当我尝试在 CentOS 机器上的应用程序服务器上从 jrxml 呈现 PDF 时，我都会收到“java.io.IOException：读取字体数据时出现问题”。使用 Jaspersoft Studio 5.6.0 生成报告。我怀疑它甚至与字体无关，因为使用没有任何字体的报告时结果是相同的。
它在 Windows 和 Ubuntu 12.04 上运行良好。
配置：
- CentOS 6.5
- Java 1.8
- 野蝇 8.1.0
- 春天 4.0.3
- 贾斯珀报告 5.6.0
到目前为止我已经尝试过：
- 添加标志：java.awt.headless = true
- 更改临时文件夹的权限
- 以 root 身份运行 AS
- 使用没有样式和字体的裸 jrxml
- 安装 MSCore 字体（在系统和 JRE 文件夹中）

在抛出异常之前在 CentOS 上调试输出：
