I wonder when and why the exception-handling code moved from `InvocationTargetException::getTargetException` to `InvocationTargetException::getCause`? 🤔

Ah, API documentation of [InvocationTargetException](https://docs.oracle.com/en/java/javase/21/docs/api/java.base/java/lang/reflect/InvocationTargetException.html#getTargetException()) to the rescue:

> API Note:
This method predates the general-purpose exception chaining facility. The [Throwable.getCause()](https://docs.oracle.com/en/java/javase/21/docs/api/java.base/java/lang/Throwable.html#getCause()) method is now the preferred means of obtaining this information.
