@Override
public LogManager run() {
LogManager mgr = null;
String cname = null;
try {
cname = System.getProperty("java.util.logging.manager");
if (cname != null) {
try {
@SuppressWarnings("deprecation")
Object tmp = ClassLoader.getSystemClassLoader()
.loadClass(cname).newInstance();
mgr = (LogManager) tmp;
} catch (ClassNotFoundException ex) {
@SuppressWarnings("deprecation")
Object tmp = Thread.currentThread()
.getContextClassLoader().loadClass(cname).newInstance(); <--------------
mgr = (LogManager) tmp;
}
}
} catch (Exception ex) {
System.err.println("Could not load Logmanager \"" + cname + "\"");
ex.printStackTrace();
}
if (mgr == null) {
