I've had a consultancy staff a large project with "senior Java developers" that we threw out the day they arrived on site because they couldn't pass a trivial coding test. This went on for a while until the consultancy became irate. While it might be nice to blame this on Java, I'm certain that if the leading enterprise language was ADA, we'd see ton's of marginally talented ADA developers being staffed. Whatever the dominant language is, you'll see a stark talent bell curve emerge around it.Think about it, if you can get a six figure salary by saying you know something, folks will say they know whatever it takes to get the job.
