Take this with a grain of salt, but...

You have to admit it's a funny item:

AN INSIDER AT Sun Microsystems says there's frantic discussion inside the company about big problems with the Java platform that, he claimed, "prevent general acceptance of Java for production software within Sun". He said: "It strikes me as hypocritical for Sun to blame Microsoft for any failure of the Java platform when Sun's own engineers find developing common software applications in Java impractical".

One of the problems, he claimed, is that while Java has a lot of benefits compared to C and C , its implementation on Solaris makes it difficult to deliver reliable applications.

I'm not sure the website here is the most reliable source, but I did get a chuckle out of this.
