Interesting, on there they said try with +PrintCompilation ... Here is 
the LoopTest written in Java:

And here is the LoopTest written in Java.

   1       java.lang.String::hashCode (60 bytes)
   2       java.lang.String::charAt (33 bytes)
   3       java.lang.String::indexOf (166 bytes)
   1%      LoopTest::main @ 7 (23 bytes)

And here is the class compiled by Josl:

   1       java.lang.String::hashCode (60 bytes)
   2       java.lang.String::charAt (33 bytes)
   1%      JoslProgram::main @ 6 (18 bytes)
   1   COMPILE SKIPPED: compile failed (not retryable)

That may have something to do with it... However, I don't know why it 
failed :-(
