[infinispan-issues] [JBoss JIRA] (ISPN-3092) AutoNodeSelector throws ArrayIndexOutOfBoundsException when indexName is long

AutoNodeSelector throws ArrayIndexOutOfBoundsException when indexName is long ----------------------------------------------------------------------------- Key: ISPN-3092 URL: https://issues.jboss.org/browse/ISPN-3092 Project: Infinispan Issue Type: Bug Reporter: Wouter De Borger Assignee: Mircea Markus When hibernate search is used (with capedwarf for example), adding a fourth server to the cluster crashes infinispan. I've narrowed the problem down to org.hibernate.search.backend.impl.jgroups.AutoNodeSelector:78 Here the following formula is used to calculate an array index int selectionRange = members.size() - 1; int selected = ( indexName.hashCode() % selectionRange) + 1; if indexname is long (like "default_taskworker-java__com.google.appengine.api.datastore.Entity") the hashcode becomes negative due to integer overflow, resulting in a negative index
