[jira] [Commented] (JCS-119) replace synchronized blocks by java locks or concurrenhashmap
[ https://issues.apache.org/jira/browse/JCS-119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=14117979#comment-14117979 ] Romain Manni-Bucau commented on JCS-119: [~yogu13] sure and yes java 6 replace synchronized blocks by java locks or concurrenhashmap - Key: JCS-119 URL: https://issues.apache.org/jira/browse/JCS-119 Project: Commons JCS Issue Type: Improvement Reporter: Romain Manni-Bucau Fix For: jcs-2.0 A cache is typically used in a concurrent environment. Since Java 6 using a ReentrantLock is faster than synchronized so can be interesting to replace synchronized blocks by a lock. Places i'm thinking about: * CompositeCache * AbstractDoubleLinkedListMemoryCache * LHMLRUMemoryCache * DoubleLinkedList * LRUMap * SingleLinkedList * SortedPreferentialArray Some places where replacing a HashMap by a ConcurrentHashMap can allow to get rid of synchronized without needing a lock: * CacheEventQueue * AbstractDiskCache * CacheWatchRepairable There are other places but this is the main I saw. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

The class Javadoc does not state whether it is intended to be thread-safe or not, but I would expect the class might be called from multiple threads. One solution would be to make the field volatile. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
