Chapter 6. Known and Resolved Issues 6.1. Known Issues BZ-1200822 - JSR-107 Support for clustered caches in HotRod implementation When creating a new cache (which is not defined in server configuration file) in HotRod implementation of JSR-107, the cache is created as local only in one of the servers. This behavior requires class org.jboss.as.controller.client.ModelControllerClient to be present on the classpath. As a workaround use a clustered cache defined in the server configuration file. This still requires cacheManager.createCache(cacheName, configuration) to be invoked before accessing the cache for the first time. BZ-1204813 - JSR-107 Support for cacheResolverFactory annotation property JCache annotations provides a way to define a custom CacheResolverFactory , used to produce CacheResolver ; this class's purpose is to decide which cache is used for storing results of annotated methods; however, the support for specifying a CacheResolver is not provided yet. As a workaround, define a CDI ManagedCacheResolver which will be used instead. BZ-1223290 - JPA Cache Store not working properly on Weblogic A JPA Cache Store deployed to WebLogic servers throws a NullPointerException after the following error message: This is a known issue in Red Hat JBoss Data Grid 6.6.0, and no workaround exists at this time. BZ-1158839 - Clustered cache with FileStore (shared=false) is inconsistent after restarting one node if entries are deleted during restart In Red Hat JBoss Data Grid, when a node restarts, it does not automatically purge entries from its local cache store. As a result, the Administrator starting the node must change the node configuration manually to set the cache store to be purged when the node is starting. If the configuration is not changed, the cache may be inconsistent (removed entries can appear to be present). This is a known issue in Red Hat JBoss Data Grid 6.6.0, and no workaround exists at this time. BZ-1114080 - HR client SASL MD5 against LDAP fails In Red Hat JBoss Data Grid, the server does not support pass-through MD5 authentication against LDAP. As a result, the Hot Rod client is unable to authenticate to the JBoss Data Grid server via MD5 is the authentication is backed by the LDAP server. This is a known issue in Red Hat JBoss Data Grid 6.6.0 and a workaround is to use the PLAIN authentication over end-to-end SSL encryption. BZ-1024373 - Default optimistic locking configuration leads to inconsistency In Red Hat JBoss Data Grid, transactional caches are configured with optimistic locking by default. Concurrent replace() calls can return true under contention and transactions might unexpectedly commit. Two concurrent commands, replace(key, A, B) and replace(key, A, C) may both overwrite the entry. The command which is finalized later wins, overwriting an unexpected value with new value. This is a known issue in Red Hat JBoss Data Grid 6.6.0. As a workaround, enable write skew check and the REPEATABLE_READ isolation level. This results in concurrent replace operations working as expected. BZ-1293575 - Rolling upgrade fails with keySet larger than 2 GB Rolling upgrades fail if the key set is larger than 2 GB of memory. The process fails when calling recordKnownGlobalKeyset because the keys cannot be dumped into a single byte array in the source cluster. This is a known issue in Red Hat JBoss Data Grid 6.6.0, and no workaround exists at this time. BZ-1300133 - JMX attribute evictions is always zero in Statistics and ClusterCacheStats MBeans The evictions attribute of Statistics and ClusterCacheStats components of the Cache MBean return zero even though some eviction operations have been successfully performed. This issue only affects statistics, not the actual eviction process. This is a known issue in Red Hat JBoss Data Grid 6.6.0, and no workaround exists at this time. BZ-1273411 - Cannot access cache with authorization enabled when using REST protocol When authorization is configured for a cache, then any access to the cache via REST endpoint results in a security exception. A user is not able to access the cache since the security Subject representing the user is not properly defined, and the user cannot be authorized to access the cache. This is a known issue in Red Hat JBoss Data Grid 6.6.0, and no workaround exists at this time. Report a bug
