I have written a small open source Java library for facilitating conversions between different types of objects (in the style of Google's gson, but quite more general).
It seems to me that a nice natural name for my library is JConverter, after browsing in the web to see if another library with the same name already exists, I found a library with the same name for Joomla.
My concrete question is:
How important is to avoid naming collisions when creating an open source library if an existing library with the chosen name already exists in a complete different domain ? (in my concrete case, these are libraries even implemented for different languages).
