[jboss-jira] [JBoss JIRA] (WFLY-3456) Can not call method with generic type parameter with null value
[

Trond G. Ziarkowski commented on WFLY-3456:
-------------------------------------------
I think that the fix implemented for this issue is wrong.
According to [~dmlloyd]s comment above, the most general method should be chosen and to me
that is {{getLastUpdate(Object)}}. Since bridge methods are filtered
{{getLastUpdate(Object)}} is not wrapped, and {{getLastUpdate(SimpleOrder)}} is the only
candidate available and the changes made in {{resolveAmbiguousWrapper(...)}}, that would
have chosen {{getLastUpdate(Object)}}, will never be executed.
The filtering of all bridged methods also has the side effect of filtering
"visibility" bridged methods as commented by [~bodist].
Since I am not able to reopen this issue I have created WFLY-6280 to address this.
