Hi,
When I write a Testcase to make a proformance test for Apache ftp server,
and I only use ONE ftp account in many threads to upload different files, then
after about 10 users loged in,
it throws exception:
[2009-04-14 09:30:52,973] [WARN ] DefaultFtpHandler [[email protected]]
[125.88.130.8] - RequestHandler.service()
java.lang.NullPointerException

most likey a thread lock problem?
