英文:
Problem when running a .jar on Linux Mint 21.1
问题
我尝试运行一个.jar文件，使用java -jar file.jar，但我得到这个错误信息：
异常在线程"main"
java.awt.HeadlessException: 未设置X11 DISPLAY变量，
或未找到Headful库支持，
但该程序执行了需要它的操作。
我不知道如何修复它，我尝试了export DISPLAY=:0，但它不起作用。
编辑：
我发现我还安装了另一个Java JDK版本（11），我尝试使用该版本运行它，它可以工作，但现在我有另一个问题。我尝试运行的.jar文件（来自Jason的jedit.jar）告诉我一个文件是59.0，而JDK 11只支持最大55.0文件。如何安装JDK 17？
编辑：
我安装了JDK 17，它可以工作。
而且我必须说，显然Java JDK 19存在问题，那是我除了11之外安装的版本。
英文:
Iḿ trying to run a jar file using java -jar file.jar and I get this message `[error] main:
Exception in thread "main"
[error] main: java.awt.HeadlessException:
[error] main: No X11 DISPLAY variable was set,
[error] main: or no headful library support was found,
[error] main: but this program performed an operation which requires it
I don´t know how to fix it, I tried export DISPLAY=:0 but it doesn´t work.
EDIT:
I found out that I had also installed another java JDK version (11) and I tried to run it with that version, and it worked, but now I have another problem. The .jar that Iḿ trying to run (jedit.jar from Jason) says me that a file is 59.0 and JDK 11 only supports maximum 55.0 files. How can I install the JDK 17??
EDIT:
I installed JDK 17 and it worked.
And I have to say that clearly there`s a problem with java JDK 19, that was the version that I have installed apart from 11.

有问题的是Java JDK 19版本，我安装了17版本，问题得以解决，我不太清楚原因。
英文:
There was a problem with Java JDK 19 version, I installed the 17 one and problem solved, I don´t know exactly why.
