["Geertjan Wielenga (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NETBEANS-3234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16949987#comment-16949987 ] 

Geertjan Wielenga commented on NETBEANS-3234:
---------------------------------------------

{quote}//Fails in NetBeans 11.1 on oracle jdk11.0.4
//Succeeds with NetBeans platform 8.2 on oracle jdk1.8.0_162
assert annot != null;{quote}

I can reproduce, but not when I run NetBeans 11.1 on JDK 8.

>             Project: NetBeans
>          Issue Type: Bug
>    Affects Versions: 11.1
>            Reporter: Boris Heithecker
>            Priority: Blocker
>
> If a package-info element is defined in some package, it cannot be properly accessed at runtime:  
>  
> java.lang.Package p = AnyClass.class.getPackage();
>  
> should return a package object representing the actual package-info element of that package. It is, for example, used by the JAXB runtime to read XmlSchema annotations at package level. 
>  
> This has been tested in oracle jdk11.0.4. Class java.lang.Package in Java 11 has a private field called "packageInfo" of type "Class<?>", which should hold a reference to the actual package-info class object, i.e. AnyPackage.package-info. In NetBeans, always wrongly references "java.lang.Package$1PackageInfoProxy", which is a fallback reference set if no actual package-info could be found. 
>  
> The reason is most likely that neither 
>  
> org.netbeans.JarClassLoader
> nor org.netbeans.ProxyClassLoader
> nor org.netbeans.StandardModule$OneModuleClassLoader (all in platform/o.n.bootstrap)
>  
> override method "java.lang.ClassLoader.findClass(String name)". The default implementation throws an exceptions which causes the above fallback reference to be set. 
>  
> This is a serious issue. If it is not fixed, the platform will not be fully comptabile, among others, with the JAXB RI and also JAX-WS RI.
