Message Title

In our webapp, we are using Ehcache as Hibernate cache region factory AND as method cache using Spring annotation @Cacheable. In our case we have single CacheManager with single ehcache.xml, which contains both kinds of regions - Hibernates and Springs. We are also using Terracotta for non Hibernates regions only.

When hibernate create CacheManager by hibernate.cache.region.factory_class, it is using HibernateUtil.loadAndCorrectConfiguration(url) method.

org.hibernate.cache.ehcache.internal.util.HibernateUtil.java

public static Configuration loadAndCorrectConfiguration(URL url) {
        Configuration config = ConfigurationFactory.parseConfiguration( url );
        if ( config.getDefaultCacheConfiguration().isTerracottaClustered() ) {
            if ( ValueMode.IDENTITY
                    .equals( config.getDefaultCacheConfiguration().getTerracottaConfiguration().getValueMode() ) ) {
                LOG.incompatibleCacheValueMode();
                config.getDefaultCacheConfiguration()
                        .getTerracottaConfiguration()
                        .setValueMode( ValueMode.SERIALIZATION.name() );
            }
            setupHibernateTimeoutBehavior(
                    config.getDefaultCacheConfiguration()
                            .getTerracottaConfiguration()
                            .getNonstopConfiguration()
            );
        }

        for ( CacheConfiguration cacheConfig : config.getCacheConfigurations().values() ) {
            if ( cacheConfig.isTerracottaClustered() ) {
                if ( ValueMode.IDENTITY.equals( cacheConfig.getTerracottaConfiguration().getValueMode() ) ) {
                    LOG.incompatibleCacheValueModePerCache( cacheConfig.getName() );
                    cacheConfig.getTerracottaConfiguration().setValueMode( ValueMode.SERIALIZATION.name() );
                }
                setupHibernateTimeoutBehavior( cacheConfig.getTerracottaConfiguration().getNonstopConfiguration() );
            }
        }
        return config;
    }

In this method NonstopCache timeout behavior is ALWAYS changing on 'exception', even if that region isn't Hibernates.

org.hibernate.cache.ehcache.internal.util.HibernateUtil.java

   private static void setupHibernateTimeoutBehavior(NonstopConfiguration nonstopConfig) {
        nonstopConfig.getTimeoutBehavior().setType( TimeoutBehaviorType.EXCEPTION.getTypeName() );
    }

1) log WARN when that happend, and keep original behavior
or
2) add property with list of regions names which allow for not default ('exception') timeout behavior.
