Description RHV bug bot 2019-09-24 10:41:45 UTC

+++ This bug is a downstream clone. The original bug is: +++
+++   bug 1754490 +++
======================================================================

As a part of EAP 7.2.4 there was upgrade of jackson library which disables deserializations of common classes and following exception is thrown:

org.codehaus.jackson.map.JsonMappingException: Illegal type (java.util.ArrayList) to deserialize: prevented for security reasons

This is similar issue which was raised in RHV 3.6 when EAP 6.4.20 was released. This issue was mitigated on RHV side (BZ1580319 and BZ1577407), but AFAIR it was decided that this is only mitigation for EAP 6.4.z and in EAP 7 will be used the fix which will not break backward compatibility.
