A very interesting point of view of Cay Horstmann published on his interview at SDN:

Horstmann: When I compare blogs about C# and Java technology, I'm struck by the differences in tone. Many C# bloggers talk about the latest goodie that came from the heavens at Redmond and how they might use it. But the Java technology bloggers write about why something is no good and needs to be improved. Now it could be that C# is such a wonderful creation that no one needs to complain. But I don't think so. If it were, more people would use it by choice. Instead, I think that the Java community has a culture of healthy whining.

We have both the will and the means to improve things and do not passively accept what is handed to us. We don't wait for Sun or someone else to fix what doesn't work. We tinker in a thousand projects and build improved libraries, frameworks, and even new languages. The open sourcing of the Java platform will enable it to be viable for years to come.

The strong and active community behind Java has always being one of its fundamental strengths.
