public class CommitException extends Exception
A checked exception being thrown from `CDOUserTransaction.commit()` in case of commit problems such as commit conflicts.

This class is the root of an exception hierarchy that allows to determine and handle specific causes of commit problems:

        CDOTransaction transaction = session.openTransaction();

        for (;;)
        {
          transaction.getViewLock().lock();

          try
          {
            CDOResource resource = transaction.getResource("/stock/resource1");

            // Modify the model here...

            transaction.commit();
            break;
          }
          catch (ConcurrentAccessException ex)
          {
            transaction.rollback();
          }
          catch (CommitException ex)
          {
            throw ex.wrap();
          }
          finally
          {
            transaction.getViewLock().unlock();
          }
        }

Instances of this class indicate low-level technical problems such as database or network issues.
