No, it does not always do that.

If the concatenation is a compile-time constant expression, then it is performed by the compiler, and the resulting String is added to the compiled classes constant pool. At runtime, the value of the expression is the interned String that corresponds to the constant pool entry.

This will happen in the example in your question.
