I have an application SWT ap1,  and i did other application SWT ap2 that use
the antlr-3.1.3 and where there are a TextBox for write a text that will be
analice for the lexer and the parser generate with ANTLR.
I have too an application that tests ap2, and it works good, the input text
is analiced ant the AST is generated correctly, but after integrate the ap2
at menu of ap1, the "SendButton" do nothing, none function is executed, but
if i erase the block try-catch that surround
*GrammaireParser.first_instruction_return
result  = g.first_instruction()*, all the functions before this instruction
works fine..., after he sais that *Unhandled exception type
RecognitionException*, and if i let the try-catch block, i do nothing!
