>Description:
The following example is illegal because 'r' may not have
been assigned when it is concatenated. gcj does not pick 
up this error.

public class Definate
{
  int id = 2;
  
  void a()
  {
    String r;
    
    switch (id)
      {
        case 99:
	  r = "foo";
	break;
      }
    
    r += "bar";
  }
}
>How-To-Repeat:
Compile the example above.
