User Comments:
mbalin: Working with JavaSE Maven project. Changed source level and Java Platform to JDK9 then open POM.XML
in POM.XML I've inserted dependency on maven-compiler-plugin 3.6.0. This exception happened when I saved the pom.xml.

Comment 2 Martin Balin 2017-01-20 13:47:05 UTC 
Exception is later shown for any action like Clean, Build, project Open...
Comment 3 Tomas Zezula 2017-01-20 15:09:09 UTC 
Caused by old module-info.class on the module path artefact.
The module-info.class has old Module attribute which is neither supported by javac (jvm) b148+ nor by the NetBeans.
Comment 4 Martin Balin 2017-01-20 15:13:38 UTC 
Interesting. The project was created with latest daily build, then source and Java platform switched to 9 and JDK9 EA b151. Then module-info added and compiled. 1st compile is done using maven-compiler-plugin 3.1. After that it has to be changed to 3.6.0 and then CCException appeared.

The old module-info.class Module attribute does not cause an CCE, the attribute is ignored.

Integrated into 'main-silver', will be available in build *201701220001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
