While updating an existing project from Wildfly version 26.0.0 to 26.1.1 I noticed that my rich client using RMI to communicate with the server does no longer work! I always get a stack trace like following:

After long research I found out the reason: The used jboss-client.jar file. Just using the old one from Wildfly 26.0.0 folder bin/client with a file size of 24.8 KiB is working, using the new one from Wildfy 26.1.1 with a file size of 19.7 KiB produces the upper exception. Yes, I do not use maven, I use the jboss-client.jar, delivered with Wildfly.{}

I am not aware of making something special with my RMI access. I checked it against a tutorial in the web and all looks ok.

As sayed, it worked since years, starting with Wildfly 8.1, I think. But with this version change I had this problems and my only workaround so far, is using the old (and larger) JAR file.{}
