Martijn Dashorst created ISPN-12100: --------------------------------------- Summary: NPE when retrieving statistics Key: ISPN-12100 URL: https://issues.redhat.com/browse/ISPN-12100 Project: Infinispan Issue Type: Bug Components: Hibernate Cache, WildFly Server Affects Versions: 9.4.18.Final Reporter: Martijn Dashorst When retrieving the statistics of infinispan caches I get a NullPointerException at the following place: {code:java} java.lang.NullPointerException at org.infinispan@9.4.16.Final//org.infinispan.stats.impl.StatsImpl.<init>(StatsImpl.java:54) at org.infinispan@9.4.16.Final//org.infinispan.cache.impl.CacheImpl.getStats(CacheImpl.java:1405) at org.infinispan@9.4.16.Final//org.infinispan.cache.impl.AbstractDelegatingAdvancedCache.getStats(AbstractDelegatingAdvancedCache.java:301) at org.infinispan@9.4.16.Final//org.infinispan.stats.impl.CacheContainerStatsImpl.getStats(CacheContainerStatsImpl.java:617) at org.infinispan@9.4.16.Final//org.infinispan.stats.impl.CacheContainerStatsImpl.getRequiredMinimumNumberOfNodes(CacheContainerStatsImpl.java:138) {code} This is while accessing the statistics through the cachemanager through the code below: {code:java} @ApplicationScoped public class InfinispanService { @Resource(name = "java:comp/env/infinispan/hibernate/entity") private Cache<?, ?> entityCache; public void stats() { EmbeddedCacheManager cacheManager = entityCache.getCacheManager(); cacheManager.getStats().getRequiredMinimumNumberOfNodes(); } } {code} This is done in wildfly 19.0.1.Final, running using standalone.xml. Obviously I'm digging into internals but probably this should not throw a NPE. The workaround is of course not calling getRequiredMinimumNumberOfNodes() (as in this particular case that is not configured IIUC). -- This message was sent by Atlassian Jira (v7.13.8#713008)
