系统：macbook pro｜mac OS Big Sur 11.2.3
kettle版本：7.1和9.1都尝试过，出现的问题都一样；
JDK：网上多半讲的这个问题是JDK版本的问题；所以我尝试了好几个JDK版本：jdk1.8.0_291.jdk、jdk1.8.0_202.jdk等（其他的删除了不记得版本号了，都是1.8.0_*）；
java -version输出：
java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)
swt.jar也下载替换过（否则会出现闪退问题）；
lib的jar包是（也换版本尝试过）：mysql-connector-java-5.1.48-bin.jar、mysql-connector-java-5.1.48.jar
spoon.sh文件中把：x86_64改成了arm64；
报错详情：
