have to agree with this. I think the core JAVA language, while pretty good,
has a few warts. I really wish Sun had spent a little more time on the core
language *before* trying to make it into a platform for everything.

JAVA is easy to use, as compared to C++ etc.... it allows for much faster
development. That said, it is all too easy to design applications that
don't performs well. You *can* design very scalable server software in
JAVA, but it requires roughly the same amount of thought as designing
a good CORBA based system does.

A pretty good example was a project I was slightly involved with: the folk
the team did a quick performance comparison and found JAVA acceptable (about
10-15% slower than C++). Problem was, they didn't really test method
and especially method invocation through interfaces. Even with some of the
good JIT's that are around now, this is *much* slower (sometimes up to 7x
than the corresponding C++ call (call to a virtual abstract base class).
seen a similar thing with threading... people use threads willy nilly
thinking through the design.

JAVA is a great language for prototyping, but at the end of the dat, good
application design requires a bit more than just easy to use tools.
