Keith Wall updated QPID-6412:
-----------------------------
Status: Reviewable (was: In Progress)
> Declare variables as ConcurrentMap not ConcurrentHashMap to avoid issues
> after compiling on Java 8
> --------------------------------------------------------------------------------------------------
>
> Key: QPID-6412
> URL: https://issues.apache.org/jira/browse/QPID-6412
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker, Java Client, Java Common
> Affects Versions: 0.32
> Reporter: Keith Wall
> Assignee: Alex Rudyy
> Fix For: 6.0 [Java]
>
>
> Java 8 redefines the method keySet() on ConcurrentHashMap to return a
> narrower type than the standard return type given in the Map interface. If
> the code is compiled in Java 8 and then run under Java 7 this causes linking
> issues.
> Avoid these issues by always declaring variables in terms of the interface
> ConcurrentMap
