Shorter is better.

I also like the ambiguity around whether or not you pronounce the H.

Of course you do, because that makes it sound like the Hispanic pronunciation of Java.

Unless you speak Spanish and then it would sound like Ava, which is conveniently not a word already.

Oops? When I ask Google Translate to pronounce Java in Spanish, I can hear the H. Is that wrong?

It’s correct, but Hava would be pronounced Ava.
