[JAVA] Try-catch blocks should not be nested - False Positive - try-catch block inside lambda

[Adam Gabryś]

Hi,

Rule S1141 Try-catch blocks should not be nested is raising a false positive for lambda expression which declares try-catch block and is located in inside another try-catch block.

Environment:

• SonarQube: 5.6.6
  
• SonarJava plugin: 4.12.0.11033

Example class:

https://github.com/agabrys/sonarqube-falsepositives/blob/master/src/main/java/biz/gabrys/agabrys/sonarqube/falsepositives/d20170926/S1141.java

Project:

https://github.com/agabrys/sonarqube-falsepositives

Build:

mvn clean package sonar

Hey Adam,

Thanks for the feedback (and reproducer! I like your github repo listing them a lot, useful!).

 It's of course a FP. We should have handled lambdas the same way we excluded anonymous classes, indeed. 

Ticket created: SONARJAVA-2487

Cheers,

Michael
