like the fruit, but have no idea what it is...

I want to plant another one of these plants, but I cannot find it on the internet. It was sold to me as a "tree tomato". It is growing fine in jungle soil with no cultivation. It is not a tamarillo, or other type (google) tomato tree. It has large leaves. It has small spiny hairs covering entire plant including the fruit. The fruit is round and looks a tamarillo when you cut into it. It tastes like a cross between a really delicious lime, and a tomato. Any idea what this is? Thanks.
