| This class is responsible for instantiating the correct LogChute |
| </p> |
| |
| <p> |
| The approach is : |
| </p> |
| <ul> |
| <li> |
| First try to see if the user is passing in a living object |
| that is a LogChute, allowing the app to give its living |
| custom loggers. |
| </li> |
| <li> |
| Next, run through the (possible) list of classes specified |
| specified as loggers, taking the first one that appears to |
| work. This is how we support finding logkit, log4j or |
| jdk logging, whichever is in the classpath and found first, |
| as all three are listed as defaults. |
| </li> |
| <li> |
| Finally, we turn to the System.err stream and print log messages |
| to it if nothing else works. |
| </li> |
