known issues with nio?

["Evans, Jess" <JE...@collegeboard.org>]

Are there any known issues with log4j 1.2.8 and new IO?  I started
receiving this error from an EJB in our production environment.  A
restart resolved the issue, but now I'm trying to determine a root
cause.  It seems that char set encoders are not thread-safe, so I'm
wondering if that is the issue.  However, I've never experienced any
issues logging from an EJB in the past.  Any suggestions would be
appreciated.
