connect to new cluster throw IndexOutOfBoundsException
I'm using Infinispan 5.3, when I disconnect from current cluster A and connect to a new cluster B, the program throw IndexOutOfBoundsException. I thought that maybe I miss something before connet to a new cluster.
Any help would be appreciated.
Here is the code snippet:
String clusterName = ((JGroupsTransport)this.cm.getTransport()).getChannel().getClusterName();
((JGroupsTransport)cm.getTransport()).getChannel().disconnect();
try {
logger.info("connet to new cluster " + clusterName + "1");
((JGroupsTransport)cm.getTransport()).getChannel().connect(clusterName + "1");
} catch (Exception e) {
logger.error("", e);
}
The following is the detail log and exception track.
