Eclipse reports on unused variables even these variables are in use

Check the screenshot from the attached file.

Unfortunately the link to tinypic.ru does not work.

Could you please provide a test case that shows the problem?
This is not the format of error/warning messages that JDT reports.

Do you have any other bundles installed ?

I use BlackBerry Eclipse Plugin and it is a project that works with this plugin.

I prepared a test case, exported it as a zip archive and tried to check (import) to be sure that issue would be reproduced on your side.

But on import all wrong reports disappeared.

I tried another way. Just tried to import an existing project to Eclipse.

But after import all wrong reports also disappeared.

Perhaps it is an IDE code caching issue or something like this.

I think the problem comes from the Blackberry bundle. It must do some validation that looks wrong.
As I said, the format of the error message doesn't look like a JDT error message.

So I would close as NOT_ECLIPSE and you should report the problem to the vendor that provides the Blackberry Eclipse plugin.

Maybe there is an update that is fixing this issue.

Please reopen if you can reproduce in a plain java project.
