User Comments:
GUEST: Triggered when auto complete function list was shown while editing a string in a PHP file

twifty: I'm getting this exception almost every time the autocomplete window pops ups.

Looking at the stack trace, I see it's happening while parsing code. Can somebody look at the trace and tell me what I should be looking for in my code. From there I may be able to provide a reproducable case.

Comment 2 twifty 2017-07-08 23:59:22 UTC
With a lot of commenting out code, I found the culprit. To reproduce, add the following to a php class.

    public function testFailsOnExistingFile()
        $tmp = new class(0, $a ? 1 : 2) {
            public function __construct($a, $b) {
        // <-- Start typing '$this' here

So long as the anonymous class exists in the source, the autocomplete will throw the exception (it doesn't matter from which line).

Reporting of this error can be easily avoided by disabling assertions (which is the default in final versions of NetBeans so this error will not occur in NB 9.0 Final). Simply remove "-J-ea" from NB config file [1].

Thanks for reporting! I'll look at it.

@junichi11, did you manage to reproduce the problem with the code I gave?

> @junichi11, did you manage to reproduce the problem with the code I gave?

Yes, reproducible. Thanks for providing it. This is a formatter's problem. I've already fixed it in my local environment. I'll push my changes tonight since I cannot watch build machines now.
