thanks for any guidance or help
You do a java clean and reinstall. check the path of the java is set to the java 8. if still you see the same issue, you can do a restore from your backup with java8.
Just FYI:
Before we upgrade JDK please refer the supported software sections which will help in making decisions..
https://docs.apigee.com/release/supported-software
Not enough data to suggest but try reading below & restore.
https://docs.apigee.com/private-cloud/v4.18.05/how-reinstall-and-restore-components
next time try to follow below to be safer.
