DriverProxy now implements Driver.getParentLogger() Otherwise, the plugin would not run with database-drivers compiled for Java 1.7. This method must not be annotated with @Override, because otherwise, the plugin won't compile under Java 1.6 (the method was added to the interface Driver in Java 1.7).
Attribute "skip" is no initialized with value of property maven.test.skip If one runs hibernate4:export with the switch "-Dmaven.test.skip=true", the configured database was droped, although the execution of the tests was skipped. This might lead to serious data-loss, if one builds a project on the production-machine. Hence, the excecution of hibernate4:export is aborted now, if maven.test.skip is true.
