It "just grew that way" I think. Sesame, for example, was developed in
Java simply because the company that builds it (Aduna) did all of its
software development in Java (platform independence was a big thing for
them at the time the project was started). 

Also, I think that projects like Sesame and Jena were started at a time
when for example Python was not quite as mature as it is today (though
I'm not sure about that, not being a Python expert). The Java platform
has long had excellent support for web application development.

I know this gets bandied around a lot, but it's really a myth. Java is
at least comparable in performance to any modern compiled language. Of
course, _badly programmed_ Java is slow, but then, so is badly
programmed C or LISP.

De gustibus and all that :)

But these days there's a plethora of good tools (or even ports of tools)
to choose from, in a variety of languages.
