[Ivy (Wang)]

• Sonarqube (Data Center Edition v2025.4.3 (113915))

• Java

• A custom rule base on rule template S3546

Parameters:

closingMethod: java.io.InputStream#close
constructor: java.io.InputStream

Hi,

Welcome to the community and thanks for this report!

I suspect this rule was never updated for the “newfangled” try-with-resources syntax. I’m going to flag this for the language experts.

Thank you for reporting this issue! Yes, it looks like try-with-resources is not supported with this rule. I created a ticket to track this issue: JAVASE-163.
