Google is a major Java shop, and for big projects compatibility is certainly at the top of requirements because big codebases last for a long time, and compatibility directly translates to increased future returns on investment. I don't think .NET quite matches Java on the other aspects (certainly it tries to add lots of language features while Java tries to avoid adding many features, but having more or fewer features is a matter of personal preference) and its GCs aren't as good, but while these things are arguable (because Java and .NET have different advantages and disadvantages compared to each other), its compatibility story is poor, and not just in comparison to Java.
