[antlr-interest] Error in the method specialStateTransition(int, IntStream)

[Jim Idle]

SPL_CHARS  :  ('\U0000' .. '\UFFFF')+;


The '+' in this means match everything and keep matching everything. You
cannot use + here, you need:

SPL_CHARS  : .;

Then use SPL_CHARS+ in your grammar not (.)+

Though I think you would be better writing a small piece of code to
process this really; ANTLR is a bit overkill for "set x y"
