GUEST: I get randomly this error. I am working on C++ projects, so it isn't related with my code. I'm unable to figure out which action triggers this.

ParserResult class cannot be loaded because:

WARNING [org.netbeans.ProxyClassLoader]: Will not load class org.netbeans.modules.csl.spi.ParserResult arbitrarily from one of ModuleCL@33d2db0c[org.netbeans.modules.csl.api] and ModuleCL@5b16b277[org.netbeans.modules.csl.types] starting from ModuleCL@3a791fba[org.netbeans.modules.cnd.script]; see http://wiki.netbeans.org/DevFaqModuleCCE

Probably result of split csl module (https://hg.netbeans.org/cnd-main/rev/47f3838c54ef).

Reassign to evaluation

Exception also happens in java code.
I can trigger the code this way:
- open Netbeans java project => Exception
- close Projets  tab (from windows > projects)
- re-enable Windows > projects => Exception

1st time I got this exception, it came from HTMLParser, so I decided to install HTML Project support plugin.

2nd time the exception was related to : org.netbeans.modules.css.lib.api.CssParserResult, so I decided to install HTML5 plugin to see what happens

3rd time the exception is related to ModuleCL, and I filed a separate bug (id #826177 for it)

It may be related to old plugins carried over from previous installations, or it may just be a bunch of exceptions occuring one after the other.

What is your netbeans version? This seems like netbeans has different versions of modules, I recommend clean reinstall of netbeans if you have problems.

All my exception were occurred on current trunk version.

It seems the bug was introduced in the change set:47f3838c54ef
IMHO two modules have the same public packages.
See:
module csl.types, public packages:
org.netbeans.modules.csl.api
org.netbeans.modules.csl.spi

module csl.api, public packages:
org.netbeans.modules.csl.api
org.netbeans.modules.csl.spi

There is no the issue evaluation. Upgrade to P2 as potential show stopper.
Comment 11 Milutin Kristofic 2016-09-02 09:46:51 UTC 
I will look at this, sorry, there was just couple reports, it never happened to me, so I was thinking it is just mess from update.
Comment 12 Svata Dedic 2016-10-25 07:34:10 UTC 
The dev version of csl.api provides no spi.ParserResult class. Please check that your NetBeans has an up-to-date version of the module, or even replace the module manually. Check your csl-api.jar contents, whether it contains  org.netbeans.modules.csl.spi.ParserResult (it should not, it was split away).

Your log indicates that installed csl.api has version 2.54.x (nbms-and-javadoc-474-on-20160507), while csl.types is nbms-and-javadoc-517-on-20160618

The CSL module split was merged in around Jun 09 2016, which is between those two originating builds. csl.api spec version was not increased at that time; it was bulk increased in Sep 2016 after code freeze, se 8.2 release should be fine.
