when code generates gotos and the compiler is forced to emulate using a while loop the label for the loop contains a - which is not valid in javascript.

phi7 = var1;
    phi8 = (var2) | 0;
    phi9 = (var3) | 0;
    phi10 = (var4) | 0;
    L-179391256: while(true) {
     var11 = (phi10) | 0;
     var12 = (phi6) | 0;
     if (var11 >= var12) {
      // line number 35

i would say label.replace("-","") should do the trick.

In case you are interested where this appears:
I$partition$$Ljava$lang$Object$$I$I$Ljava$util$Comparator$ This is probably an incompatability that does not exist in java8
