| * This is a very bad stream handler for the MAudit task. |

| * The limitation with the choosen implementation is clear: |
| * <ul> |
| * <li>it does not handle multiline report( message that has \n ). the part until |
| * the \n will be stored and the other part (which will not match the pattern) |
| * will go to Ant output in Warn level. |
| * <li>it does not report error that goes to stderr. |
