java: lac: check it

Browse Source 
* tests/calc.at: Add tests for LAC in pull and push parsers.
Skip LAC: line from the logs.
* tests/local.at (reportSyntaxError): Output the error message in a
single call, to avoid having the error message on stderr be
interrupted by the debug traces of LAC in getExpectedTokens.
