Hi all, we recently noticed that the Apache MINA FTPServer will log an javax.net.ssl.SSLHandshakeException when the server does not have a valid certificate. The complete stracktrace from the log files is listed below. Since it is logged on the MINA-side, it doesn’t even reach my section of the Java code.
Is there a way to suppress the logging of this particular Exception while
retaining the loggings of other WARNINGs?
Cheers,
Martin
