使用带有openjdk的stix-fonts的例外？

Question

我尝试创建时出现问题SXSSFWorkbook.

异常堆栈跟踪:

java.lang.ArrayIndexOutOfBoundsException: 0
    at sun.font.CompositeFont.getSlotFont(CompositeFont.java:351)
    at sun.font.CompositeGlyphMapper.initMapper(CompositeGlyphMapper.java:81)

    at java.awt.font.TextLayout.<init>(TextLayout.java:531)
    at FontTest.main(FontTest.java:15)

gradle文件:

compile 'org.apache.poi:poi:3.14'
compile 'org.apache.poi:poi-ooxml:3.14'

环境 :

• openjdk版本"1.8.0_141"
• RedHat 7.4
• wildfly 10.0.0

这个问题只发生在Red hat version 7.4.据报道那里.红帽子们正在努力解决这个问题.我找到的解决方案就是提供字体以强制将Utopia作为java使用的默认字体.

/etc/fonts/local.conf使用以下内容创建以下文件:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
  <alias>
    <family>serif</family>
    <prefer><family>Utopia</family></prefer>
  </alias>
  <alias>
    <family>sans-serif</family>
    <prefer><family>Utopia</family></prefer>
  </alias>
  <alias>
    <family>monospace</family>
    <prefer><family>Utopia</family></prefer>
  </alias>
  <alias>
    <family>dialog</family>
    <prefer><family>Utopia</family></prefer>
  </alias>
  <alias>
    <family>dialoginput</family>
    <prefer><family>Utopia</family></prefer>
  </alias>
</fontconfig>

确保正确的用户可以读取该文件.
