ttf：
OTF：
两者都是相同的字体,但字体文件类型不同
根据Adobe的Miguel Sousa的说法,该错误不在字体中
https://github.com/adobe/source-sans-pro/issues/32#issuecomment-23319673
我只是将默认字体设置为新字体. TTF版本可以正常使用
Font font_o = Font.createFont(Font.TRUETYPE_FONT, fonts.class.getResourceAsStream("fonts/TTF/SourceSansPro-Regular.ttf"));
//Font font_o = Font.createFont(Font.TRUETYPE_FONT, fonts.class.getResourceAsStream("fonts/OTF/SourceSansPro-Regular.otf"));
Font font_n=font_o.deriveFont(Font.PLAIN, UIManager.getLookAndFeelDefaults().getFont("defaultFont").getSize());
UIManager.getLookAndFeelDefaults().put("defaultFont",font_n);
为什么线高有所不同？

结论(forums.oracle.com/thread/2573652 similair和他在那里的帖子一样多,没什么特别的)
>不是Java,也不是Nimbus错误,这是Font中的错误,您可以看到在Metal,Win,WinClassic和Nimbus Laf中,OTF_Font在字形上方缺少2个像素
. Windows.
.金属.
.雨云.
.经典.
Java6上的WinXp
