Hi,
I'm trying to make Apache Chemistry OpenCMIS work on Java 9. OpenCMIS
relies on CXF 3.0.5 (because we need to support Java 6).
Connecting to a Web Service fails on the server with the following stack
trace.
java.lang.LinkageError: loader constraint violation: when resolving
overridden method
"org.apache.cxf.jaxb.attachment.JAXBAttachmentUnmarshaller.getAttachmentAsDataHandler(Ljava/lang/String;)Ljavax/activation/DataHandler;"
the class loader (instance of
org/mortbay/jetty/webapp/WebAppClassLoader) of the current class,
org/apache/cxf/jaxb/attachment/JAXBAttachmentUnmarshaller, and its
superclass loader (instance of sun/misc/Launcher$ExtClassLoader), have
different Class objects for the type javax/activation/DataHandler used
in the signature

Do you already have plans for Java 9? Have you done any testing?
I don't want open an issue in JIRA for something that nobody has looked
at, yet.
Thanks,
Florian
