Hi,

I am getting the following error while looking up EJB in JDK 16. It works fine in JDK 8.

Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make field private static final java.lang.reflect.Method jdk.proxy29.$Proxy136.m0 accessible: module jdk.proxy29 does not "opens jdk.proxy29" to unnamed module @182f9a0

This should be fixed in the WF24.

=> https://issues.redhat.com/browse/WFLY-14668

=> https://github.com/wildfly/jboss-ejb-client/pull/513

=> Released in jboss-ejb-client-4.0.41.Final which is part of WF24

Hi,

Wildfly 24 is still on org.jboss....@4.0.39.Final and not on 4.0.41

Are you sure, that you started WF 24?

Your stacktrace contains entries pointing to a WF 23 installation (like org.jboss.as.ejb3@23.0.0.Final)
I just downloaded a fresh archive of the normal WF 24 (as I'm using WF 24 preview) and it really contains 4.0.41.Final and not 4.0.39.Final

Ensure that your JBOSS_HOME environment variable, etc is setup correctly. Maybe it points to an older installation and mixes up WF 24 with WF 23.

Hi,

My EJB server is 23 but I upgraded jboss-client.jar on client with jboss-client.jar shipped with wildfly24.0.0.Final.

I can see following line is coming from jboss-client.jar:24.0.0.Final:

at org.jboss....@4.0.39.Final//org.jboss.ejb.client.EJBClient.createProxy(EJBClient.java:156) ~[jboss-client.jar:24.0.0.Final]

Do I need to upgrade server also?

Thanks,

Jasvant

Hi,

I do see that Wildfly24 ships jboss-ejb-client:4.0.41 in modules but in jboss-client.jar it might be shipping jboss-ejb-client:4.0.39.

I am connecting to wildfly server from client which is running inside tomcat 9.

Thanks,

Jasvant
