Throwable targetException = var6.getTargetException()

This code retrieves the target exception that was thrown by the specified invocation target.
In Java, when a method is invoked using reflection, the invoked method may throw an exception. Instead of throwing the exception directly, the method wraps the exception in a InvocationTargetException and throws it.
To retrieve the original exception, you can use the getTargetException() method of the InvocationTargetException. This code assigns the target exception to a Throwable variable named targetException.

Throwable targetException = ex.getTargetException();
在给定的代码片段中,`Throwable targetException = ex.getTargetException();`是获取`InvocationTargetException`中的目标异常对象。`InvocationTargetException`是在反射调用方法时可能抛出的异常,它包装了实际方法调用中抛出的异常。通过`getTargetException()`方法,我们可以获取到实际的目标异常对象,然后可以对其进行进一步处理或抛出。
