求助:J2SE中繪畫異常問題.....

swallow0804

今天在測試的時候發現一個新問題:
      繪畫時將字體改為粗體、斜體，然后不斷刷新、調用就會出錯!
     
       異常時處死機狀態，除以上錯誤，會拋出以下異常:
       Exception in thread "AWT-EventQueue-0" java.lang.InternalError: Win32OSSD_Lock cannot nest locks

Problem:
I noticed your comment on the bottom of Creating and Deriving Fonts regarding bug 4155852. This bug has been closed with no action taken. Is it true that you can't apply a style to fonts such as Arial?
The problem is that font-to-style matching is not working properly for physical fonts (such as Arial or Palatino). You can only apply styles to logical fonts at this point (such as Dialog or SansSerif). As a workaround until the bug is fixed, you could do the following:
Font f = new Font("Palatino Bold", Font.PLAIN, 12);

instead of:
                  
Font f = new Font("Palatino", Font.BOLD, 12);


But. how to solve it ?
