rednaxelafx opened a new pull request #29875: URL: https://github.com/apache/spark/pull/29875
### What changes were proposed in this pull request? Use `Utils.getSimpleName` to avoid hitting `Malformed class name` error in `TreeNode`. ### Why are the changes needed? On older JDK versions (e.g. JDK8u), nested Scala classes may trigger `java.lang.Class.getSimpleName` to throw an `java.lang.InternalError: Malformed class name` error. Similar to https://github.com/apache/spark/pull/29050, we should use Spark's `Utils.getSimpleName` utility function in place of `Class.getSimpleName` to avoid hitting the issue. ### Does this PR introduce _any_ user-facing change? Fixes a bug that throws an error when invoking `TreeNode.nodeName`, otherwise no changes. ### How was this patch tested? Added new unit test case in `TreeNodeSuite`. Note that the test case assumes the test code can trigger the expected error, otherwise it'll skip the test safely, for compatibility with newer JDKs. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
