             Summary: Reintroduce support for configuring a JChannel via URL
                 Key: JGRP-2477
                 URL: https://issues.redhat.com/browse/JGRP-2477
             Project: JGroups
          Issue Type: Enhancement
    Affects Versions: 5.0.0.Beta1, 4.2.3
            Reporter: Thomas Darimont
            Assignee: Bela Ban


Infinispan 9.4.x (9.4.19) uses a URL to load the JGroups configuration from the infinispan configuration.
When an external jgroups stack configuration file is used: 
See: "Using an external JGroups file" in https://infinispan.org/docs/9.4.x/user_guide/user_guide.html#using_an_external_jgroups_file

When creating the JGroups stack, infinispan uses the constructor in org.jgroups.JChannel#JChannel(...) which takes a URL as parameter.
See: https://github.com/infinispan/infinispan/blob/9.4.x/core/src/main/java/org/infinispan/remoting/transport/jgroups/JGroupsTransport.java#L586

However this constructor is only present in versions up-to including 4.0.22 https://github.com/belaban/JGroups/blob/4.0.22/src/org/jgroups/JChannel.java#L121
and was removed in later versions. 

Because of this users of infinispan 9.4.x, who use the "Using an external JGroups file" configuration approach cannot upgrade to new JGroups versions, like 4.2.3.
In order to ease upgrading to newer JGroups versions with Infinispan 9.4.x. it would be very kind if the constructor with the URL parameter
could be added back.

I created two pull requests to add the constructor  {org.jgroups.JChannel#JChannel(java.net.URL)} to master, as well as the 4.x branch.
