Use synchronized blocks for ApplicationImpl _defaultValidatorsIds
-----------------------------------------------------------------
Key: MYFACES-2805
URL: https://issues.apache.org/jira/browse/MYFACES-2805
Project: MyFaces Core
Issue Type: Improvement
Components: JSR-314
Affects Versions: 2.0.0
Reporter: Leonardo Uribe
Assignee: Leonardo Uribe
Right now we have a ConcurrentHashMap for ApplicationImpl
_defaultValidatorsIds, but we are using a _cachedDefaultValidatorsIds too. In
this case, it is better to use a synchronized block when default validators are
added, but use a double-checked locking using volatile on the cache. Not use a
synchronized block causes that getDefaultValidatorInfo() could return not all
validators, but note that posibility is unlikely.
