Betreff: Re: [equinox-dev] JAXB with Java 11 in OSGi

Hi Neil, Dmytro and Mark,

I tried this but I'm still getting the ClassNotFound Exception.

I uploaded a tiny example here:
https://github.com/vogellacompany/eclipsercp-jaxb-java11

In case you want to test, clone the repo, import the example into
Eclipse and activate the jaxbtarget.target definition and start the
application via the com.vogella.jaxb.product.

Press the button called "Trigger JAXB"

Results in ClassNotFoundException

Caused by: java.lang.ClassNotFoundException:
org.eclipse.persistence.jaxb.JAXBContextFactory at
java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:602)
at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178)

Best regards, Lars
