Geting java.awt.AWTError:无法用JRE-8连接到HP-unix上的X11窗口服务器

Question

在HP上使用JRE 8运行基于GUI的java应用程序时，我得到以下错误：

Exception in thread "main" java.awt.AWTError: Can't connect to X11 window server using 'ravkumar-t430.apac.tibco.com:1.0' as the value of the DISPLAY variable.

但是，一旦我使用了JRE 7而不是JRE 8，那么问题就解决了，应用程序就可以了。

当我在应用程序中设置java.awt.headless=true属性时，它会给出java.awt.headless异常。

请给我建议解决办法。

Answer 1

这是HP操作系统中的一个bug，它会给X11显示64位JRE带来问题。此问题在安装最新的OS修补程序PHSS_43291后得到解决。

43291&sp4ts.oid=3367737

这个问题有两种解决办法：

1/要么切换到32位jre

2/在11.31上安装最新的修补程序。
