"Java has no free() or delete operators, so it has to rely on tracking variable scope to find out when variables are no longer used (together with references to these variables of cause)." - While true, this not relevant. C and C++ have free / delete operators respectively, and yet the equivalent C / C++ code to your examples would be illegal. C and C++ blocks limit the scope of variables just like in Java. In fact, this is true for most "block structured" languages.

The better solution for code that assigns a different value on every branch is to use a blank final variable declaration.
