Error with java

[ksteflovic]

I can't do any kata in java, I always get this error, also, see here (https://www.codewars.com/kata/do-i-get-a-bonus/discuss/java):

Looks like an issue due to the new underlying GroovyServ implementation, implemented to make builds faster. Other kata I have tested seem to be working, I'm not sure why this one fails.

I'm working on some other updates to the underlying implementation so I will make sure to test this before I push it out.

[OverZealous]

The above error doesn't seem to be related to the Kata you linked. (I could be wrong, I just didn't see that error when trying to run it with a simple solution that always returns "".)

The linked kata is referencing some Unicode characters which seem to be returning this error:

/home/codewarrior/BonusTimeTest.java:31: error: unmappable character for encoding ASCII
      System.out.println("\u00A3 == ??:"+"\u00A3".equals("??"));

In the tests it looks like

System.out.println("\u00A3 == £:"+"\u00A3".equalsIgnoreCase("£"));

My guess is, at least in this scenario, the compiler is not liking the embedded Unicode characters. Not sure why the updated runner would change this.

[OverZealous]

@jhoffner Looks like we might need to pass in the encoding of the source files? I'm not sure if the old runner was doing that automatically.

This should be fixed now isn't it @jhoffner @kazk ???

@javatlacati Thanks.
