[~dkwakkel] I believe [~romain.manni-bucau] is right.
The problem here is that some of the MP libs require Bean injection on their
Extensions. So, the Extension is loading, but their CDI beans are not, hence
you get that weird NPE.
Most likely, the CDI Extensions are being loaded by one class loader and their
beans scanning by another loader, or not even scanned at all.
Can you have a look here
org.apache.openejb.config.DeploymentLoader#addBeansXmls(org.apache.openejb.config.WebModule).
This is where the url list of jars is obtained to perform CDI scanning for
beans. So, it needs to return all the MP libs in here.

[~dkwakkel] nop, this does not look the same issue like that. ParentClassLoader
must be openejb classloader and never the TCCL of an app (it must not be able
to load any app class to be concrete but only server libs except when all are
in the same flat classloader). Here the issue is that the scanned loader does
not match your custom loader strategy since we just respect webapp strategies.
Using WEB-INF/jars.txt or openejb classloader customizer would work since the
scanning and runtime will them use the same list of jars.

I found a similair issue about tccl not used here: TOMEE-877.
[~romain.manni-bucau] is this the same issue?

When adding above line to MyClassLoader [^myclassloader.jar.withtccl] :
{code}
package test;
import java.net.URL;
import java.net.URLClassLoader;
import org.apache.catalina.loader.WebappClassLoader;
public class MyClassLoader extends WebappClassLoader {
public MyClassLoader(ClassLoader parent) throws
java.net.MalformedURLException {
super(parent);
addURL(java.nio.file.Paths.get(System.getProperty("catalina.home"),
"myexception.jar").toUri().toURL());
org.apache.openejb.loader.SystemInstance.get().setComponent(org.apache.openejb.core.ParentClassLoaderFinder.class,
fallback -> java.lang.Thread.currentThread().getContextClassLoader());
}
private static URL[] getURLss(){
try {
return new URL[]{new
URL("file:///C:/Program%20Files/TomEE/myexception.jar")};
}
catch(Exception e) { throw new RuntimeException(e); }
}
}
{code}
and adding a bean to the myexception.jar which is loaded through this
classloader [^myexception.jar.withbean]:
{code}
package test;
import static javax.ejb.TransactionAttributeType.SUPPORTS;
import java.util.function.Supplier;
import javax.ejb.LocalBean;
import javax.ejb.Singleton;
import javax.ejb.TransactionAttribute;
import javax.xml.ws.Provider;
@Singleton(name = "PlatformContextBean")
@LocalBean
public class PlatformContextBean> implements Provider
{
@SuppressWarnings("unchecked")
@Override
@TransactionAttribute(SUPPORTS)
public T invoke(T request) {
Object result = request.get();
return (T) (Supplier) () -> result;
}
}
{code}
I get the following exception from Micro Profile:

When adding following in MyClassLoader it is working:
{code:java}
SystemInstance.get().setComponent(ParentClassLoaderFinder.class,
fallback -> Thread.currentThread().getContextClassLoader());
{code}
I would expect ParentClassLoaderFinder returns tccl by default.
