3. I checked the information and found no solution, but I was reminded that it may be a problem with the jdk version, so I re-downloaded jdk1.8 from the official website decisively

And modify the original configuration back

1. Many people will encounter the exception of memory overflow
2. Environment variables are not configured properly
3. The number of jdk digits is inconsistent with that used by kettle
4. In other cases, it is largely a jdk version problem, you can uninstall and try another version
