LocalCommitConflictException
public class CommitConflictException extends ConcurrentAccessException
A concurrent access exception that indicates that some of the local modifications are based on old revisions because other transactions have intermittently committed their modifications.

It's usually possible and adequate to rollback the transaction, replay the model modifications and commit the transaction again (optimistic strategy). Pessimistic locks can help to avoid the problematic situation (see also CDOAutoLocker).

Instances of this class indicate commit conflicts that are detected in the repository. They can also occur if a conflict resolver is used locally (network race condition).

For detection of local commit conflicts see LocalCommitConflictException.
