[mod_cluster-issues] [JBoss JIRA] (MODCLUSTER-142) Use UUID for auto-generated jvmRoute

Use UUID for auto-generated jvmRoute ------------------------------------ Key: MODCLUSTER-142 URL: https://issues.jboss.org/browse/MODCLUSTER-142 Project: mod_cluster Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: 1.1.0.CR1 Reporter: Paul Ferraro Assignee: Paul Ferraro Fix For: 1.1.0.CR2 Currently, auto-generated jvm-routes are of the form: bind-address:port:engine-name This exposes internal addresses/ports and is not appropriate for production systems. To fix that, we can use UUIDs. e.g. InetAddress connectorAddress; int connectorPort; String engineName; int addressBytes = connectorAddress.getAddress().length; int intBytes = Integer.SIZE / Byte.SIZE; int charBytes = Character.SIZE / Byte.SIZE; ByteBuffer buffer = ByteBuffer.allocate(addressBytes + intBytes + (engineName.length() * charBytes)); buffer.put(connectorAddress.getAddress()); buffer.putInt(connectorPort); buffer.asCharBuffer().put(engine); String jvmRoute = UUID.nameUUIDFromBytes(buffer.array()).toString(); I can think of 2 disadvantages: 1. UUID jvm-routes will be, on average, longer than the current default, i.e. 36 characters as opposed to ~28. Not a significant difference there. 2. For development, exposing the address and port via the jvm route might be useful. To satisfy this requirement, we can make the use of UUIDs configurable.
