Description Martin Hardy CLA 2010-04-23 05:26:00 EDT 
Build Identifier: 20100218-1602

Even when the "ignore in overriding and implementing methods" option is checked for the "parameter is never read" compilation option, a warning is raised for implementing methods that don't use one of their parameters.

Reproducible: Always

Steps to Reproduce:
1. Create an interface with a method that receive any parameter.
2. Create a class that implements first step interface with an empty implementation for the method.
3. Choose "warning" for "Unnecessary code\Parameter is never read" in "Java/compiler/"Errors/warnings" preferences.
4. After applying, a rebuilt is done raising a warning on unused parameter in implementing method created in step 2. That is normal.
5 Now, check the "ignore in overriding and implementing methods" option and apply. After the rebuild, the warning is still here, which is not normal.

It works for me using I20100414-1200.
Please provide a test case and make sure you are using a newer build.
I cannot retrieve the build 20100218-1602 anymore.
Thanks.

Thanks for answer.
I'm currently out of work for health reasons until may 10th.
I'll check that then.

Any update ?
Comment 4 Martin Hardy CLA 2010-05-20 09:01:01 EDT 
I tried to update my eclipse but build id didn't change in "About" window.
I'm using Eclipse for RCP/plug-in Developers.

In "installed software" tab of "installation details, its version is "Eclipse for RCP/Plug-in Developers	1.2.2.20100216-1730	epp.package.rcp". A click on the "Update" button for this line answers "nothing to update".

Note : I run Eclipse using java 1.6 but compiles using java 1.5 compliance level.

Closing as WORKSFORME since I cannot reproduce anymore.
