```
public static Throwable getMostSpecificCause(Throwable original)
```
    Retrieve the most specific cause of the given exception, that is, either the innermost cause (root cause) or the exception itself.
    Differs from getRootCause(java.lang.Throwable) in that it falls back to the original exception if there is no root cause.

    original - the original exception to introspect
    返回:
    the most specific cause (never null)
