  - dummyLevel
```
protected static final Level dummyLevel

    This member variable simply ensures that any attempt to initialise this class in a pre-1.4 JVM will result in an ExceptionInInitializerError. It must not be private, as an optimising compiler could detect that it is not used and optimise it away.
