DmitriyB. updated SYNCOPE-1386:
-------------------------------
Description:
Hi guys. I noticed the issue that leads to inconsistent data that comes in HTTP
response.
In Apache Syncope the Application Scoped Entity manager is used for all
operations with the database. Entity manager is created by appropriate Entity
Manager Factory that matches a particular domain. Thus, the scope of
Persistence Context is extended and also it is bound to a current thread.
Moreover, Entity Manager that is created by Entity Manager Factory is
Transactional. Thus any execution using entity manager without opened
transaction leads to exception like (which is fine):
{code:java}
java.lang.IllegalStateException: Could not find EntityManager for domain

In Apache Syncope L2 cache is enabled by default.
syncope-core-persistence-jpa-2.0.8.jar!\domains.xml file has a property
{code:java}
<entry key="openjpa.DataCache" value="true"/>
{code}
If the transaction is opened, the entity, that is fetched via Entity Manager
gets into L1 cache and L2 cache and becomes managed.
If an exception occurs L1 cache is being destroyed because Entity Manager is
bound to a current thread. Managed entity becomes detached. But L2 cache can
have this detached entity.
Here is an example of code where it can be reproduced.

Here is the use-case how to reproduce the problem:
1. Create user in Syncope
2. Do a request password reset action and make sure that token that is used for
pwd reset action is generated and stored into database.
3. Restart your application to be sure that L2 cache is empty.
4. Confirm password reset action for this user and make sure that requested
password doesn't apply the password rules. In my case password is too short.
The exception like "InvalidUser:InvalidPassword: Password too short" should be
thrown.
5. Request the user by username. The user that comes in HTTP Response doesn't
have "token" and "tokenExpireTime" attributes. But you may find "token" and
"tokenExpireTime" value in SyncopeUser table for this user.
