             Summary: Apache NetBeans running on JDK 11 cannot access package 
                 Key: NETBEANS-3234
             Project: NetBeans
          Issue Type: Bug
    Affects Versions: 11.1
            Reporter: Boris Heithecker

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$1PackageInfoProxy", which is a fallback reference set if no 
actual package-info could be found. 
The reason is most likely that neither 
nor org.netbeans.ProxyClassLoader
nor org.netbeans.StandardModule$OneModuleClassLoader (all in 
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.
