---------------------------------

             Summary: Thread unsafe use of HashMap for cached mappings exist
                 Key: ROL-2101
                 URL: https://issues.apache.org/jira/browse/ROL-2101
             Project: Apache Roller
          Issue Type: Bug
          Components: Data Model & JPA Backend
    Affects Versions: 5.1.2
            Reporter: Kohei Nozaki
            Assignee: Roller Unassigned
            Priority: Minor


There are two singleton classes that have a instance field type of {{HashMap}} for cache.

In {{JPAUserManagerImpl}}:
{noformat}
// cached mapping of userNames -> userIds
private Map<String, String> userNameToIdMap = new HashMap<String, String>();
{noformat}

In {{JPAWeblogEntryManagerImpl}}:
{noformat}
// cached mapping of entryAnchors -> entryIds
private Map<String, String> entryAnchorToIdMap = new HashMap<String, String>();
{noformat}

{{HashMap}} s should not be used as the above because it's not thread safe.
