> Key: NETBEANS-3234
> URL: https://issues.apache.org/jira/browse/NETBEANS-3234
> Project: NetBeans
> Issue Type: Bug
> Affects Versions: 11.1
> Reporter: Boris Heithecker
> Assignee: Eric Barboni
> Priority: Critical
> Labels: pull-request-available
> Fix For: 11.3

> Time Spent: 2h 40m
> Remaining Estimate: 0h

> 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.
