I really like the code inspection functionalities which are now able with either JSR 305 or Jetbrains' proprietary annotations for IntelliJ. Unfortunately both implementations (JSR 305 and Jetbrains') do not mix well:
The only possible workaround might be to go for JSR-305 and use the Findbugs plugin in IntelliJ. Has anybody a better idea? (please don't say change your IDE ;) ).
Thanks Thomas
This has been made possible with the 10.5 of IntelliJ: http://blogs.jetbrains.com/idea/2011/03/more-flexible-and-configurable-nullublenotnull-annotations/
