JasperSoft Studio初始化字体时出现问题

Question

总之，我在Jaspersoft Studio中编辑我的Jasper报告时遇到了问题，显示了以下异常。

Could not initialize class
com.jaspersoft.studio.preferences.fonts.utils.FontUtils

为了导致错误，我所要做的就是尝试编辑任何文本字段或静态文本。下面是我的报告和项目fonts.jar文件中的fonts.xml。我尝试使用的字体是Roboto，包含在JasperSoft的首选项部分，我必须包含al ttf。

这发生在项目的所有报告中，这里是一个示例。

Answer 1

由于字体不可用而发生错误。工作室给我同样的错误。问题解决了。在处理 ireport 5.0 或 ireport 5.6 时，我从未得到过这个，可能是因为我正在使用的 java 版本或已经配置了字体路径的某些版本。碧玉工作室窗户 -

或者你也可以试试下面的选项，有些适合你。

1. Switched from Open JDK to Sun JDK
2. Installed MS Core Fonts
3. Packaged JasperReport font library jar with the application

出现问题的主要原因是字体
