| Which AST parse level should I be using? [message #268851] |

I know that I create a parse with the following code:
ASTParser p = ASTParser.newParser(AST.JLS3);
p.setSource(unit);
CompilationUnit u = (CompilationUnit) p.createAST(null);
This, of course, fails because 1.5 parsing is not yet supported. The
question is, how do I choose the correct parse level? Once 1.5 parsing is
supported, shouldn't there be a setting somewhere that allows me to NOT do
1.5 level compilation? Shouldn't I be getting the current parse level from a
more static location? Has that location already been implemented and I just
haven't found it? Is my code up above totally screwed?

The code, as given, does not solve the problem. This still fails with an
exception because Java 1.5 is not supported. I am looking for something that
will allow my code to work even when 1.5 is supported. I have always heard
that you shouldn't use exceptions to handle code flow but it seems that that
is what I am being forced into.
