Error description
Although the key manager (KeyManagerImpl) is already synchronized, a race condition can occur if the key manager is serialized, for example, during session fail-over. The race condition can result in hanging threads or seemingly corrupt data structures as the key manager uses a access-ordered LinkedHashMap which results in structural changes even if the map is only accessed with get() methods. This APAR supersedes PM02025.
Local fix
None available.
Problem summary
Although the key manager (KeyManagerImpl) is already synchronized, a race condition can occur if the key manager is serialized, for example, during session fail-over. The race condition can result in hanging threads or seemingly corrupt data structures as the key manager uses a access-ordered LinkedHashMap which results in structural changes even if the map is only accessed with get() methods. This APAR supersedes PM02025.
Problem conclusion
This APAR introduces specialized writeObject/readObject methods that properly deal with the synchronization during serialization.
