(was: Are your sure your solution passes with the fix and does not without it?
I've tried it and changed my test case according to your suggestion. If I
comment out the ProxyClassLoader.findClass(String name) override, the test
still passes, regardless if run with java 8 or 11.0.4.
(I did some digging in the existing sources before as well, and, though I may
not have been thorough enough, it seems to me that you can't easily create a
unit test for this fix. You'd have have to change more code in ProxyClassLoader
only for the sake of testing.))
> Apache NetBeans running on JDK 11 cannot access package classes
> ---------------------------------------------------------------
>
> Key: NETBEANS-3234
> URL: https://issues.apache.org/jira/browse/NETBEANS-3234
> Project: NetBeans
> Issue Type: Bug
> Affects Versions: 11.1
> Reporter: Boris Heithecker
> Priority: Critical
> Labels: pull-request-available
> Fix For: 11.3
>
> Time Spent: 1h 50m
> 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.
