update sample tests, fix Java tests (#20300)

* replace removed forkMode

* remove junit runner where it's not needed

* update samples without skipping test files, but skip files named "FILES"

* revert overwriting custom tests, add custom java tests to list

* add one sample to CircleCI, fix various Java tests
