JBoss Messaging throws an java.lang.IllegalArgumentException exception ----------------------------------------------------------------------- Key: JBMESSAGING-1913 URL: https://issues.jboss.org/browse/JBMESSAGING-1913 Project: JBoss Messaging Issue Type: Bug Components: JMS Client Manager Environment: JBoss EAP 5.1.2 Reporter: Tom Ross Assignee: Yong Hao Gao The code for org.jboss.jms.client.plugin.RoundRobinLoadBalancingPolicy.getNext() method calls Random.nextInt(int n) with negative argument. This is wrong since the Java JDK 1.6 documentation states that the nextInt(int n) method must be called with a positive number. This is method implementation as per JDK 1.6 documentation. public int nextInt(int n) { if (n <= 0) throw new IllegalArgumentException("n must be positive"); if ((n & -n) == n) // i.e., n is a power of 2 return (int)((n * (long)next(31)) >> 31); int bits, val; do { bits = next(31); val = bits % n; } while (bits - val + (n-1) < 0); return val; }
