George Vasiliu commented on AXIS-2937:
--------------------------------------
Thanks for the reply!
We will see if the v1.6.4 could be a valid solution. You mentioned the axis2
1.8 trunk client code still has references there, so it won't work, but is
there some estimation/plan on fixing this in future versions ? (eg. we might
consider waiting for that version)

> Hello everyone,
>
> We are upgrading our project and intend to keep the axis-2 1.6.2 distribution
> we were using. Until now, we were using JDK 8 to compile & run the project,
> now we have switched to JDK 11 and for only 1 webservice project we have, it
> fails with the error seen in the attached file.
>
>
> I have already scrubbed the surface with
> https://issues.apache.org/jira/browse/AXIS2-5966 and
> https://issues.apache.org/jira/browse/AXIS2-5935, however, those fixes are
> intended for 1.8.0, whileas we would like to add this patch for the 1.6.2
> version, as there are many breaking changes between 1.6.2 and 1.8.0 (that
> cause alot of validation tests to fail for XML messages due to the parser
> inside axis2 and other issues).
>
> Do you have any recommendations on how to approach this issue? If possible,
> we would like to get the patch for 1.6.2 and build with maven ourselves and
> keep it in our internal nexus as a patched jar, however, we do not know the
> necessary changes to the ClassReader.java class that need to be done to make
> it work.
>
> If there is a possible workaround that can be done outside axis 2 (ie. modify
> our webservices in a certain way) to make it work, we are also open to that.
>
> Besides that, to confirm the issues, we compiled the entire project under
> jdk11, but that particular sub-project was compiled under jdk8, when starting
> the server the error is no longer shown, so a conclusion : compiling the
> project under jdk11 breaks it when running the server. The server is a JBoss
> 7.2.6 one.
>
> Note that the project that fails actually contains a lot more webservices, it
> only fails for that very specific one. I will come back with an update
> regarding whether java7/8/9/10/11 features are used in the classes inside,
> however, I doubt it.
>
> The axis2.xml for the project has the following deployers configured :
> !image-2020-03-27-10-46-17-413.png|width=782,height=173!
>
> So no .aar being deployed, issue is caused by a .class from somewhere.
