【问题描述】：

我正在使用 IDEA 来完成一些关于 JSF 的任务。我只是用 glassfish 运行一个简单的项目，输出是这样的：

the out put

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/glassfish/admin/cli/AsadminMain has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

google了一下，知道版本52就是jdk 8，所以我把其他的jdk都删了，只留下jdk8，版本确实是1.8：

the java version

C:\Users\42173>java -version
java version "1.8.0_291"
Java(TM) SE Runtime Environment (build 1.8.0_291-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.291-b10, mixed mode)

C:\Users\42173>javac -version
javac 1.8.0_291

但是还是报同样的错误，不知道怎么办。

并且我已经尝试过glassfish5，但输出仍然有错误：

exception with glassfish5

【解决方案1】：

你的错误信息是错误的。

... has been compiled by a more recent version of the Java Runtime (class file version 55.0),
this version of the Java Runtime only recognizes class file versions up to 52.0

它并没有告诉您需要 Java 8，而是告诉您 Java 8（类版本 52）太旧，无法运行由版本 55（即 Java 11）编译的类。

所以你需要安装 JDK 11。
