Is there anything specific about the file where it occurred? E.g. was it html file renamed to PHP or something like that? Did you customize the mime type 
settings?

the file is a phtml with html and a few php lines 
no customized mime.

I was just able to reproduce it myself when editing html sections in a regular PHP file.

Upgrading to P2. The exception is related to CLS migration

I'll look at it.

Can be either a bug of LanguageRegistry.getInstance().getLanguageByMimeType(mimeType) returning PHPLanguage for
text/html mimetype or more likely an issue in ResultIterator resp. its SourceCache returning a ParserResult not
generated by parser registered to ResultIterator.getSnapshot().getMimeType() mimetype.

I'll add some debug messages. Any steps to reproduce are welcomed!

debug code added in web-main#e37aeb86d5c1

hmm, that means that the CCE happens even if 

resultIterator.getSnapshot().getMimeType().equals(resultIterator.getParserResult().getSnapshot().getMimeType());

I wonder why the extra message is not logged:

SemanticHiglighter:314:

try {
        task.run(result, null);   //here the CCE happens
    } catch (Exception ex) {
            LOG.log(Level.WARNING, "SemanticAnalyzer = " + 
                    task + "; Language = " + language +
                    " (mimetype = " + language.getMimeType() +
                    "; ParserResult = " + result +
                    "(mimepath = " + result.getSnapshot().getMimePath() + ")", ex);
        }

???

this should log some more info when the CCE happens AFAIK.

I just got a user report containing the recently added debug information:

WARNUNG [org.netbeans.modules.csl.editor.semantic.SemanticHighlighter]: SemanticAnalyzer =
org.netbeans.modules.php.editor.parser.SemanticAnalysis@1e9fcf8; Language =
org.netbeans.modules.csl.core.Language@104ee8[text/x-php5 (mimetype = text/x-php5; ParserResult =
org.netbeans.modules.html.editor.gsf.HtmlParserResult@df28d2(mimepath = MimePath[text/x-php5])

According to the logged debug messages it looks like the problem is that the
HtmlParserResult.getSnapshot().getMimePath() returns (text/x-php5) instead of (.../text/html)

There are also many warnings from both Css and Javascript embeddings providers complaining that the given snapshot is
not of the expected type.

Please not that the embeddings providers are registered to all mimetypes, but the factories creates EP instance only for
text/html snapshot. So the assumption is that subsequent calls to EP.getEmbeddings(Snapshot s) will happen only for
snapshot of the same (text/html) type.

Please also note that most of the reports complains about text/x-php5 mimetype. The PhpEmbeddingProvider is registered
to text/x-php5 mimetype and then the factory.create() method makes EP instances regardless on the given snapshot.

Reassigning to Hanz since this looks like a race condition in parsing.api.

Please looks the recent exception reports messages log, for example:
http://statistics.netbeans.org/exceptions/messageslog?id=185229

The issue is random, but already we have 102 duplicate exception reports.

Wow, lots of duplicates, I'd say this is a P1.

I can not reproduce it. Yes, there are many duplicates. On the other hand - its RANDOM, no data loss. So, P2 is more
accurate, I think.

*** Issue 161014 has been marked as a duplicate of this issue. ***

This issue has already 250 duplicates 
see http://statistics.netbeans.org/exceptions/detail.do?id=148002

Happens very often to me. I'm ready to run NB with logging enabled and I'm sure I will be able to trap it very soon
again. So, is it possible to provide some logging aiming to find the cause?

I have found reproducible usecase, so I will fix it soon. Thanks for your offer.

looks like its fixed in 0fcec879498e
