      ---------- BEGIN SOURCE ----------
      public class FooBar {

          // run: javac -g:vars FooBar.java
          public static void COMPILER_GOES_BOOM() {
              { // need to have a block here.
                  //int before = 0; // assigning values here and it compiles fine,
                  int i;
                  int j;
                  if (Boolean.valueOf("true")) {
                      i = 1;
                      System.out.println(i);
                  }
                  if (Boolean.valueOf("true")) {
                      j = 2;
                      System.out.println(j);
                  }
                  // int after; // comment in and it compiles fine.
              }
          }

      CUSTOMER SUBMITTED WORKAROUND :
      change the code so the variable scope changes
