I don't like the idea to automagically disable indexing on a Cache, when the user might have explicitly enabled it via configuration.

If we do such a thing, then I'd go for option 1

Deadlock in InfinispanDirectoryProvider startup ----------------------------------------------- Key: ISPN-5270 URL: https://issues.jboss.org/browse/ISPN-5270 Project: Infinispan Issue Type: Bug Components: Embedded Querying Affects Versions: 7.2.0.Alpha1, 7.1.1.Final Reporter: Dan Berindei Assignee: Gustavo Fernandes Priority: Minor Attachments: surefire.stacks, surefire2.stacks The InfinispanDirectoryProvider tries to start the metadata, data, and locking caches when it starts up, with {{DefaultCacheManager.startCaches()}}. However, when one of these caches (e.g. the metadata cache) starts, the {{LifecycleManager.cacheStarting()}}, which can then try to start the InfinispanDirectoryProvider again: {noformat} "CacheStartThread,null,LuceneIndexesMetadata" prio=10 tid=0x00007f5f74484000 nid=0xe42 in Object.wait() [0x00007f5efff48000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) - waiting on <0x00000000c2180000> (a org.infinispan.manager.DefaultCacheManager$1) at java.lang.Thread.join(Thread.java:1281) - locked <0x00000000c2180000> (a org.infinispan.manager.DefaultCacheManager$1) at java.lang.Thread.join(Thread.java:1355) at org.infinispan.manager.DefaultCacheManager.startCaches(DefaultCacheManager.java:465) at org.hibernate.search.infinispan.spi.InfinispanDirectoryProvider.start(InfinispanDirectoryProvider.java:84) at org.hibernate.search.indexes.spi.DirectoryBasedIndexManager.initialize(DirectoryBasedIndexManager.java:88) at org.hibernate.search.indexes.impl.IndexManagerHolder.createIndexManager(IndexManagerHolder.java:256) at org.hibernate.search.indexes.impl.IndexManagerHolder.createIndexManager(IndexManagerHolder.java:513) - locked <0x00000000ce6001d0> (a org.hibernate.search.indexes.impl.IndexManagerHolder) at org.hibernate.search.indexes.impl.IndexManagerHolder.createIndexManagers(IndexManagerHolder.java:482) at org.hibernate.search.indexes.impl.IndexManagerHolder.buildEntityIndexBinding(IndexManagerHolder.java:91) - locked <0x00000000ce6001d0> (a org.hibernate.search.indexes.impl.IndexManagerHolder) at org.hibernate.search.spi.SearchIntegratorBuilder.initDocumentBuilders(SearchIntegratorBuilder.java:366) at org.hibernate.search.spi.SearchIntegratorBuilder.buildNewSearchFactory(SearchIntegratorBuilder.java:204) at org.hibernate.search.spi.SearchIntegratorBuilder.buildSearchIntegrator(SearchIntegratorBuilder.java:122) at org.hibernate.search.spi.SearchFactoryBuilder.buildSearchFactory(SearchFactoryBuilder.java:35) at org.infinispan.query.impl.LifecycleManager.getSearchFactory(LifecycleManager.java:260) at org.infinispan.query.impl.LifecycleManager.cacheStarting(LifecycleManager.java:102) at org.infinispan.factories.ComponentRegistry.notifyCacheStarting(ComponentRegistry.java:230) at org.infinispan.factories.ComponentRegistry.start(ComponentRegistry.java:216) at org.infinispan.cache.impl.CacheImpl.start(CacheImpl.java:814) at org.infinispan.manager.DefaultCacheManager.wireAndStartCache(DefaultCacheManager.java:591) at org.infinispan.manager.DefaultCacheManager.createCache(DefaultCacheManager.java:546) at org.infinispan.manager.DefaultCacheManager.access$100(DefaultCacheManager.java:115) at org.infinispan.manager.DefaultCacheManager$1.run(DefaultCacheManager.java:452) {noformat} This can hang the test, the attached thread dumps show {{EmbeddedCompatTest}} and {{IndexCacheStopTest}}.
