Local variable used and declared in different 'switch' branches

Reports local variables declared in one branch of a switch statement and used in another branch. Such declarations can be extremely confusing.

Example:

switch(i) { case 2: int x = 0; break; case 3: x = 3; System.out.println(x); break; }
