1.3. Upgrading from JBoss Data Grid 6.2.1 to 6.3

The following information is useful for users upgrading from Red Hat JBoss Data Grid 6.2.1 to 6.3.
Hot Rod Protocol

In JBoss Data Grid 6.3, to support the new functionality (for example, security), the Hot Rod protocol for client server communication has been changed from version 1.3 to version 2.0. If the new Hot Rod client (JBoss Data Grid 6.3.0) is used against an earlier instance of the grid (for example, JBoss Data Grid 6.2.1), the Hot Rod protocol version must be explicitly configured as follows (defaults to version 2.0): 

infinispan.client.hotrod.protocol_version=1.3
Classloader

The classloader specified using org.infinispan.configuration.cache.ConfigurationBuilder.classLoader() is ignored in JBoss Data Grid 6.3.x. Use one of the following alternatives to specify a custom classloader:

  • org.infinispan.configuration.global.GlobalConfigurationBuilder.classLoader(ClassLoader) for a global configuration.
  • org.infinispan.AdvancedCache.with(ClassLoader) for a per call configuration.
API Package Changes

For details about packages added, changed, and removed from JBoss Data Grid from the 6.2.1 release to the 6.3.0 release, see the JBoss Data Grid API Documentation.
