Windows 8.1上的SoapUI 5.6.0 UnsupportedClassVersionError

问题描述

我已经在Windows 8.1上安装了以下版本的Java。 JAVA_HOME环境变量指向新安装的JDK库。

java 15 2020-09-15
Java(TM) SE Runtime Environment (build 15+36-1562)
Java HotSpot(TM) 64-Bit Server VM (build 15+36-1562,mixed mode,sharing)

启动SoapUI 5.6时，出现以下错误消息：

java.lang.UnsupportedClassversionError: com/eviware/soapui/SoapUI has been compiled by a more recent version of the Java Runtime (class file version 53.0),this version of the Java Runtime only recognizes class file versions up to 52.0

解决方法

请查看this链接以获取修复程序，该修复程序是不同的Java版本。

requirements说Java 7，实际上建议在多个place中使用Java 8。

但是，是的，我认为错误

com/eviware/soapui/SoapUI has been compiled by a more recent version of the Java Runtime (class file version 53.0),this version of the Java Runtime only recognizes class file versions up to 52.0

对于主要的Java版本具有误导性。精通Java版本的人也许可以解释。
