Re: Making JacORB work for Java 11

Fredrik,

Thanks very much for confirming this!

I got your demonstration working and fixed the problem in our build scripts (I had missed some of the dependencies of course!).
Tests are currently running and initial results look good.

It is probably worth noting (for anyone else searching for the exception), that putting the following in the classpath:
jboss-rmi-api_1.0_spec-1.0.6.Final.jar

Will fix a start-up exception like:
Exception in thread "Thread-7" java.lang.NoClassDefFoundError: javax/rmi/CORBA/Stub

     at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:499)
     ... 14 more

(The other dependencies described in the previous messages are also needed of course).

Thanks again for your help!

I tried with openjdk11 for linux downloaded from here:
https://jdk.java.net/11/
A trivial test seems to be working. (I also noticed that jaco does not work on the latest Ubuntu, unles you replace #!/bin/sh with #!/bin/bash)

You can clone the test code here:
https://github.com/weetmuts/CorbaExperiments
put java/javac11 in your path and do: 2make", "make server" and in a different window "make client".
