Description unai 2012-09-15 07:56:03 UTC 
When editing a Java file, this hint warns about n<<0 being a pointless bitwise expression, but doesn't about 0<<n, which is equally pointless.

(I accidentally created the bug as P4 instead of default's P3)
Comment 3 unai 2014-01-09 18:07:28 UTC 
...and also 0>>n and 0>>>n, for the sake of completeness.
