[isis] 02/02: ISIS-2112: further fixing build issues, finally all 'core' modules build

This is an automated email from the ASF dual-hosted git repository.

ahuber pushed a commit to branch 2112_SpringBoot
in repository https://gitbox.apache.org/repos/asf/isis.git

commit 6615f45abed63908b42f7c85ec79777a065c024d
Author: Andi Huber <ah...@apache.org>
AuthorDate: Tue May 14 13:17:23 2019 +0200

    ISIS-2112: further fixing build issues, finally all 'core' modules build
    
    - 'objenesis' convergence, bumping 2.4 -> 2.6 'codegen-javassist'
    - phasing out plugin 'eventbus-axon' .. to be replaced by Spring
    - 'jaxb' convergence issues .. using 2.3.2
    - bumping bytebuddy 1.9.3 -> 1.9.12
    - disable 3 imposterise test, since these fail when run on jvm-11
    
    Task-Url: https://issues.apache.org/jira/browse/ISIS-2112
