Issue #201506-01: Thread-safety issues with CTS when encryption is enabled

| Fixed versions | 12.0.2 |

Description:
When the Core Token Service token encryption is enabled and the system is under a heavy load, it is possible that incorrect session/SAML/OAuth2 tokens are returned by the CTS.
Workaround:
Disable token encryption by setting the following property to false:
com.sun.identity.session.repository.enableEncryptionIn the OpenAM console via Configuration > Servers and Sites > Default Server Settings > Advanced or via ssoadm:
$ ./ssoadm update-server-cfg --servername default --adminid amadmin --password-file /tmp/pwd.txt --attributevalues com.sun.identity.session.repository.enableEncryption=falseThis setting is false by default.
Note
By changing this setting, any existing encrypted tokens stored in CTS will become unreadable by OpenAM.
Resolution:
Use the workaround or update/upgrade to a fixed version or deploy the relevant patch bundle.
