Hi all,
I've started a new thread for this, so as not to clutter the previous
thread on exceptions.
I've come across a possible issue with creating SyntaxError objects (and
potentially other exceptions although I haven't tested them).
https://gist.github.com/purplefox/dfe30a38098c1708e24b
In the above gist I create a SyntaxError specifying message, fileName,
and lineNumber.
However fileName and lineNumber appear to be ignored, and instead the
SyntaxError fileName and lineNumber are set to the fileName of the file
where it was created and the lineNumber of the creation.
I'm not sure if I'm doing something wrong, but according to
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SyntaxError
I should be able to create SyntaxError objects like this.
There appears to be a further issue. If I then throw the syntax error
from the JS script, and catch it in Java like this:
try {
engine.eval(script);
} catch (ScriptException e) {
System.out.println("message:" + e.getMessage());
System.out.println("fileName:" + e.getFileName());
System.out.println("lineNumber:" + e.getLineNumber());
}
Then the message, fileName and lineNumber always correspond to place
where the object was created, not to the subsequently set values.
In other words, I can't figure out a way of creating a SyntaxError
object in JS with my own values of fileName and lineNumber and have
those values available in Java when caught.
Any ideas from the experts? :)
