Rule "Exception handlers should preserve the original exceptions" false-positive in java 8 lambda expression (SonarQube 6, Java 4.2)

[adere...@gmail.com]

Hi all, 

With SonarQube 6 and Java Plugin 4.2 we get a false positive for the rule "ExceptiException handlers should preserve the original exceptions" in the following code fragment. handlers should preserve the original exceptionsException handlers should preserve the original exceptions

 (StreamResource.StreamSource) () -> {

                        final PipedInputStream pipedInputStream = new PipedInputStream();

                        final PipedOutputStream pipedOutputStream;

                        try {

                            pipedOutputStream = new PipedOutputStream(pipedInputStream);

                        } catch (IOException e) {

                        throw new RuntimeException(e)

                        }

};

Hey,

Just to let you know that this case will be handled while fixing issues with the semantic, as discussed in this other thread about unused local variables.

Cheers,
