I simply wished to add the fact to the existing report that updating the java to OpenJDK 7 from OpenJDK 6 is a possible solution and that this is not caused by Mojang but by the java runtime. Since the original report is unresolved, perhaps this is the reason for the bug.
Also, this bug does not only happen on 1.7.4 but also on 1.7.9. Any version 1.7.4 and later. 1.7.4, 1.7.6, 1.7.8 and 1.7.9.
When i reload the world the own is on the ground. Such as the chicken and feathers on the screen shot.
