I see.

BTW, at the beginning of SSLLogger, there is

String p = GetPropertyAction.privilegedGetProperty("javax.net.debug");
if (p != null) {
    if (p.isEmpty()) {
        property = "";
        logger = System.getLogger("javax.net.ssl");
    } else {

Will this "p.isEmpty()" ever happen? I cannot find a place when only SSLLogger.isOn is checked but not SSLLogger.isOn("something").
