java:S1612: lambda performing instanceof check is not reported as code smell

[grimsa (Gediminas Rimša)]

Versions:

• Sonarcloud.io
• Sonar Gradle plugin 3.1.1
• Java 14

In this code snippet, there are two lambdas that can be replaced with method references, yet only one is reported:

I expected to see suggestion for using StringInverterPhotovoltaicGridTieSystem.class::isInstance method reference as well.

Thanks for your feedback. I would rather say it’s not a bug this rule just doesn’t support instanceof check in lambda.

I’ve created a ticket to cover this case.
