Local variables are sometimes declared as non-existent types.

Describe the bug

Sometimes local variables are declared as types that do not exist.

Additional information

This affects old Minecraft versions. For example, class zh in the 1.0.0 client jar has a method a()[I that decompiles to the following:

    public int[] a(String string) {
        afs var2 = this.l.a;
        int[] var3 = (int[])this.e.get(string);
        if (var3 != null) {
            return var3;
        } else {
            try {
                I var6 = null;
                if (string.startsWith("##")) {
                    var6 = this.b(this.c(this.a(var2.a(string.substring(2)))));
                } else if (string.startsWith("%clamp%")) {
                    this.b = true;
                    var6 = this.b(this.a(var2.a(string.substring(7))));
                    this.b = false;
                } else if (string.startsWith("%blur%")) {
                    this.c = true;
                    this.b = true;
                    var6 = this.b(this.a(var2.a(string.substring(6))));
                    this.b = false;
                    this.c = false;
                } else {
                    InputStream var8 = var2.a(string);
                    if (var8 == null) {
                        var6 = this.b(this.m);
                    } else {
                        var6 = this.b(this.a(var8));
                    }
                }

                this.e.put(string, var6);
                return (int[])var6;
            } catch (IOException var5) {
                var5.printStackTrace();
                int[] var4 = this.b(this.m);
                this.e.put(string, var4);
                return var4;
            }
        }
    }

Notice that var6 is given type I (which does not exist), but is cast to int[] before being returned by the method.
