Description Jaromir Uhrik 2009-05-19 10:12:47 UTC 
Product Version: NetBeans IDE Dev (Build 200905190201)
Java: 1.5.0_16; Java HotSpot(TM) Client VM 1.5.0_16-133
System: Mac OS X version 10.5.7 running on i386; MacRoman; en_US (nb)

When I enter a message it sometimes takes up to ~1 minute when it appears in the messages list. When I use the native
client everything is allright, this appears only in NetBeans chat client. Not only messages send by me are late, also
messages sent by others appear late in IDE. I am attaching snapshots from profiler (switched on before Entering a
message and switched off after the message appeared in the messages list above the input textfield).

Comment 4 Jan Becicka 2009-05-19 13:02:56 UTC 
It looks like JDK bug.
???

Anyway can you test it with some other xmpp java client. Spark for instance?

socket.accept is also slow for CLIHandler... not only for chat.

Can you test on JDK 1.6?

Thanks
Comment 5 Jan Becicka 2009-05-21 13:52:00 UTC 
Need to know behavior with JDK 6 and Spark IM client
