NestedServletException (Spring Framework 4.3.30.RELEASE API)

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - javax.servlet.ServletException
    - - org.springframework.web.util.NestedServletException

All Implemented Interfaces:
Serializable
Direct Known Subclasses:
ServletRequestBindingException
```
public class NestedServletException
extends ServletException
```
Subclass of ServletException that properly handles a root cause in terms of message and stacktrace, just like NestedChecked/RuntimeException does.
Note that the plain ServletException doesn't expose its root cause at all, neither in the exception message nor in printed stack traces! While this might be fixed in later Servlet API variants (which even differ per vendor for the same API version), it is not reliably available on Servlet 2.4 (the minimum version required by Spring 3.x), which is why we need to do it ourselves.
The similarity between this class and the NestedChecked/RuntimeException class is unavoidable, as this class needs to derive from ServletException.
Since:
1.2.5
