IllegalStateException: Already undeployed

Running the sample gives an IllegalStateException: Already undeployed. This is not an problem, so maybe the exception shouldn't be logged as severe.

First, run ./mvnw clean install from the project root. Then, from the sample directory, run ../mvnw compile dependency:copy-dependencies. Lastly, run java --module-path target/classes:target/lib --module com.microsoft.gctoolkit.sample/com.microsoft.gctoolkit.sample.Main ../gclogs/preunified/cms/defnew/details/defnew.log. These steps are in the README file for the root and sample.

The XYDataSet for DefNew contains 19114 items.

Run the documented Maven build and sample command from the repository README, then trace the shutdown path through VertxChannel.close, AbstractJavaVirtualMachine.analyze, and the sample Main entry point. Determine whether the expected result is to suppress the benign Already undeployed SEVERE log while preserving the dataset output, and verify the sample no longer reports that error.
