java.lang.Object
com.nimbusds.common.infinispan.CacheWorkArounds<K,V>
public class CacheWorkArounds<K,V> extends Object
Infinispan cache workarounds.
  • Fix around invalidation bug, to force cache load before putIfAbsent, replace, delete operations. See tracking Connect2id server issue https://bitbucket.org/connect2id/server/issues/239/race-condition-in-cacheremove-in
  • Enforcing zero cache size for "stateless mode" to enable Infinispan to be run in local mode with no in-memory store, using the configured stores instead.
