---------------------------------
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.
