This looks like a non-deterministic behavior (bug) on the language side (Java & Nashorn). Perhaps the first submission will also get OK if rejudged.
You can also try adapting the I/O to JavaScript V8 and submit the solution in that language directly.
Well I used to think that there shall be no more bugs in java8 since it has been published for so long time. Maybe I am naive
