RE: ExceptionMapper is not working after upgrading to 2.7.8 from 2.5.0

[Rakesh R]

Hi,

I think I found the cause:

We had defined following three exceptions with the error codes:
               - IllegalArgumentException - err code: Response.Status.NOT_FOUND
               - IllegalStateException  - err code:  Response.Status.CONFLICT
               - InternalServerException - err code : 
Response.Status.INTERNAL_SERVER_ERROR

IllegalArgumentException & IllegalStateException  are not throwing back to the 
client and it is going to multiple retries. But I could see 
InternalServerException is getting called and propagating the exception to my 
client.

Now I have one question: Is there any behavioral change in the error codes and 
building the response messages logic.

Thanks in advance for any help.

Subject: ExceptionMapper is not working after upgrading to 2.7.8 from 2.5.0

Hi,

We have implemented the failover feature and exception mappers using cxf 2.5.0 
and now we are trying to use the latest available version 2.7.8.
After upgrading to 2.7.8 my  exception mapper logic is not working fine. Based 
on the initial analysis I could see 'response.getEntity()' is returning null 
and causing the issue.
Can anyone help me to resolve this issue.

Following is my mapper implementation:

    RestExceptionResponseMapper implements ResponseExceptionMapper<Exception> {

       public Exception fromResponse(Response response) {
              // ....
              try {
                     inputStream = (InputStream) response.getEntity();
                     reader = new BufferedReader(new 
InputStreamReader(inputStream));
                     s = reader.readLine();
              } catch (IOException e) {
                     // ....
              } finally {
                     // ....
              }
      }
   }


Failover strategy implementation:
              <failover>
                     <strategy>
                            <type>multiAttemptSequencial</type>
                            <maxRetryAttempts>3</maxRetryAttempts>
                            <tryInfinitely>true</tryInfinitely>
                     </strategy>
              </failover>

              FailoverFeature feature = new FailoverFeature();
              FailoverStrategy failoverStrategy;
              try {
                     failoverStrategy = 
applicationContext.getBean(failoverStrategyType, FailoverStrategy.class);
              } catch (BeansException e) {
                     // .....
              }


Thanks,
Rakesh
