Created attachment 213796 [details] jdt core preferences only with relevant settings Steps to reproduce: 1) Create an eclipse plugin project. 2) Set from "Java Compiler->Errors/Warnings" all settings to default and the following two settings to be reported as errors: - Unnecessary code/Unused import - Generic types/Usage of a raw type 3) In a java file add a valid import package that is not used by a code. 4) Add a statement that would use a generic type in raw form. e.g. implement IAdaptable. The method "getAdapter" will generate "Usage of a raw type" warning. 5) Build java class. I expect for java compiler to report both types of errors: usage of generic raw types and having unused imports. Actually only usage of raw types will be reported. To exacerbate the issue, when using "@SuppressWarnings("rawtypes")" no errors/warnings will be reported. Attache is jdt core preferences and a sample java file

This was done so that we don't report errors for those problems which would have required the import itself. However, I agree that this problem is slightly different and it may be good if we report both the errors. This will 'probably' fixed along with the fix for bug 371832. > > To exacerbate the issue, when using "@SuppressWarnings("rawtypes")" no > errors/warnings will be reported. > This will be fixed by bug 371832.

No, it is limited to warnings elevated to error severity
