NullPointerException with cross-site and multiple parent stacks

    XMLWordPrintable

Details

    Description

      When RELAY2 is configured and when there is multiple parent stack chained (see example), a NullPointerException is thrown that prevents the server from starting.

      <jgroups>
      <stack name="image-tcp" extends="tcp">
         <!-- not relevant -->
      </stack>
      <stack name="relay-tunnel" extends="udp">
          <!-- not relevant -->
      </stack>
      <stack name="xsite" extends="image-tcp">
         <relay.RELAY2 xmlns="urn:org:jgroups" site="a" />
         <remote-sites default-stack="relay-tunnel">
            <remote-site name="a" />
            <remote-site name="b" />
         </remote-sites>
      </stack>
   </jgroups>

      The NPE is caused by https://github.com/infinispan/infinispan/blob/4cdc8bb75eef45e8b519cfa02375b207ba05970c/core/src/main/java/org/infinispan/configuration/parsing/Parser.java#L553

      When it parses the stack xsite, remoteSites is set. Then, it goes through the parent stack image-tcp and tries to merge the removeSites. However, it is null.
