This may help, if I try to compile the parser.js I get:
christopher-thatchers-macbook-air:env-js thatcher$ java -cp rhino/
js.jar org.mozilla.javascript.tools.jsc.Main -d dist dist/parser.js
Exception in thread "main" org.mozilla.javascript.EvaluatorException:
Encountered code generation error while compiling function "null":
generated bytecode for method exceeds 64K limit. (dist/parser.js#45)

at org.mozilla.javascript.tools.jsc.Main.main(Main.java:73)
but looking at the file:
christopher-thatchers-macbook-air:env-js thatcher$ ls -lsa dist/
parser.js
592 -rw-r--r-- 1 thatcher admin 302530 Feb 14 17:38 dist/parser.js
christopher-thatchers-macbook-air:env-js thatcher$
So how can it be possible that a 31KB file exceeds a 64KB function
limit? Am I missing something here?
Thanks for any insight.
