Subject [jira] [Commented] (SUREFIRE-1424) javax.transaction.TransactionManager not visible with Java9
Date Sat, 21 Oct 2017 08:36:00 GMT


Tibor Digana commented on SUREFIRE-1424:

Again, however I understand class loading issue, the Oracle did what they planned to initially
to do. They wanted JDK/JRE to simply extend by adding jar modules. Now it is a precedence
and anything can be changed so that you would not tell that it would be Java in few years.
Java was built on fact that it was stable and not removed.
So they should rely on initial idea that {{javax}} packages and {{java.transaction}} are extensions
and should go to separate jar file files and User would download them from Oracle's {{downloads.html}}
and/or installation on Windows will interactively download it in to JRE 9 and reconstruct
what people rely on. The bad is that you {{unplugged}} modules and {{removed}} classes without
giving ability to get it back to previous status and not to accomplish the precedence.
Instead your arguments are {{because of EE}}, but it is not truth because Java Activation
and JAXB are pure static utilities and annotations which have nothing to do with container
managed app. You can easily run the utilities in {{public static void main()}}. You could
make it so dynamic that application without {{module-info}} would behave as before and all
modules are on classpath as it was in Java 8,and opposite in modular app. {{Now Surefire substitutes
this behavior and I think this is what Users want}}. But no, Oracle {{dictated}} something
and we have the problem, we have to do your job! This is the problem.
