Java版本:
JDK1.8.0_91(HotSpot(TM) 64-Bit Server VM)
系統環境:
Mac OS 10.15.4
場景描述:
用Java Swing寫了個CS版的套打小工具,實現了列印介面Printable的print方法,對於包含二維碼等圖片的列印,畫筆(Graphics)
g2.drawImage描繪圖片時候會報錯,錯誤資訊如下:

問題處理:
看到 StackOverflowError 以為執行緒記憶體大小不夠(Xss) 或者 有大物件(圖片)沒釋放,把圖片解析度大小等都調低了還是報錯!
查了下 StackOverflow 存在類似的問題:
同時也在openjdk的Bugs系統找到了該問題對應的JDK-Bug記錄:
試了下 在Window系統相同的JDK版本下 沒有這種問題
