So I finally found some time to try and dig deeper into this issue,
though I'm not very familiar with Java and NetBeans (from the developer
perspective), and issues like this make for a fairly steep learning
curve, especially since nobody's been able to help with it before.
Anyway, I think I've found an immediate reason for the this exception:
after 'ant run' for the PHP Editor module, this file gets deleted:
php/php.editor/build/classes/org/netbeans/modules/php/editor/parser/CUP$ASTPHP5Parser$actions.class
It's not being created again using 'ant build' for the module. A whole
full build is needed for that.
As for why would that file be deleted, I don't know yet, though I
strongly suspect it really shouldn't be deleted 😁
But there seems to be a trail, CUP$ASTPHP5Parser$actions.class is
mentioned in php/php.editor/nbproject/project.properties:
nbjavac.ignore.missing.enclosing=**/CUP$ASTPHP5Parser$actions.class
And searching for nbjavac.ignore.missing.enclosing reveals two things:
1. No other project.properties than PHP Editor seems to have it
2. It's being used by CustomJavac.java, in cleanUpDependDebris() method
that does seem to delete some files and its comments link to the
issue #196556: https://bz.apache.org/netbeans/show_bug.cgi?id=196556
Does this ring any bells to anybody?
From what I read, this file is supposed to be skipped from the
deletion, but apparently it's not. Could it be because **/ is not a
valid path in Windows? Is this cleaning up step also an issue in any
other modules, or is the PHP Editor somehow special? The linked Bugzilla
issue has some mentions of JDK 7 and implements a workaround for an
issue that existed ~10 years ago, maybe the whole thing is not needed
anymore? And lastly, why is this class not being recreated with 'ant
build' the module?
Thanks for whatever insights anybody might have to share.

Well, I believe that was as detailed as it can be, I did literally
nothing except for those steps I've described, can't think of anything
else...
This must be somehow related to platform (Windows - notoriously bad
for some types of development), tools (Java, Ant versions listed
below) or whatever else specific to the environment. Probably me doing
something wrong, but given the very basic steps to reproduce for me,
I'm currently out of ideas.

Hi,
no I meant detailed steps to reproduce. As said, with the provided
steps I was not able to reproduce the issue.

I've got all the Ant output from the full build, 1st run (before the
edit), 2nd run (after the edit, when the exception appears) and the
3rd
run (after reverting, exception still appears) as well as the diff
of
the edit. All made from the current master. It's too large to post as
a
gist at Github though and almost 1MB zipped. Is it okay to attach
the
zip to the mailing list?

Hi Matthias,
By being detailed, other than you've quoted, did you mean I am to
keep
track of all output from eg. ant? (at what level then?)
Thanks.

I can reproduce the issue this way:
* ant clean build (build successful)
* open PHP Editor project, change a file (I tried
InitializeFieldSuggestion.java from
org.netbeans.modules.php.editor.verification), just added
an
extra
new line, nothing else
* ant -f php/php.editor run
* open a small project with PHP sources, a dialog window
with the
exception appears almost immediately
* I can still dismiss the dialog and click around NetBeans,
but the
dialog keeps reapperaring every couple of clicks
My environment:
* Windows 10
* Apache Ant(TM) version 1.10.7 compiled on September 1 2019
Tested on Ubuntu and is not reproducible for me. Please start
with a
clean checkout from NetBeans master and be detailed what you do
and
how. Else it is pure speculation.
Greetings
Matthias
