NetBeans 11.1 with Java 11 fails to read package annotations
Hi all,
it seems that a NetBeans 11.1 platform app running on Java 11 (oracle
jdk11.0.4) doesn't read annotations at package level properly. If I'm not
mistaken for whatever reason this is a really nasty bug.
Please have a look at this to reproduce:
https://github.com/borisheithecker/packagelevelannotationtest
If I run this small platform application with platform 11.1 and Java 11
selected, it fails (i.e. the package annotation is not found at runtime).
If I run it with NetBeans 8.2 and Java 8_162 the annotation is found as
expected.
I started porting a platform application yesterday which has been run on
8.2 so far and which makes heavy use of JAXB and Web Services. I spend the
whole day digging various sources on why the application fails to run on
Java 11 (with Metro JAX WS RI added as external library) until I found out
what seems to be the obvious reason now: it fails because JAXB can't
read @XmlSchema-annotations in package-info. Am I doing something wrong?

So if I'm not taken completely wrong, the reason is that
neither org.netbeans.JarClassLoader nor org.netbeans.ProxyClassLoader nor
org.netbeans.StandardModule$OneModuleClassLoader (all in
platform/o.n.bootstrap) override "protected Class<?> findClass(String name)
throws ClassNotFoundException" in java.lang.ClassLoader. Therefore, package
classes aren't loaded.

Re: NetBeans 11.1 with Java 11 fails to read package annotations
Posted by Boris Heithecker <bo...@gmx.net>.
I got a little closer to the problem now.
So, take this line and debug it a) in plain Java 11, and b) in this
NetBeans platform (any version but running on JDK 11):
java.lang.Package p = Main.class.getPackage();
Class java.lang.Package in Java 11 differs in many aspects from Java 8. In
Java 11, it has a private field called "packageInfo" of type "Class<?>",
which in cases
a) (the working case) is a reference to the actual package-info class
object, i.e. MyPackage.package-info
b) always references "java.lang.Package$1PackageInfoProxy", i.e. the
java.lang.Package class object (and therefore NOT the class object
resulting from the compilation of e.g. MyPackage.package-info.java as it
would be supposed).
This is a bug. It's most likely a NetBeans classloader issue.

It's definitely not a JDK problem. The code works fine in a non-platform
application with jdk11.0.4. It's a problem of the combination JDK 11 plus
NetBeans Platform. It fails even if I switch to JDK 11 and NetBeans 8.2.

So first start by using the same JDK for both to see whether it is a JDK
problem (probably since JDK 11 is very different to JDK 8) or not.
