this means that log4j was not able to find any property file at all,
however it was initialized. do you set FBLog4j property to true (i
assume no, but want to be sure)?

no, i don't.

i will check this issue. log4j should not be initialized
automatically. it seems that there is some class(es) that force logger
to load log4j. if firebirdjmx.jar was ok for your needs, i would
suggest to consider firebirdsql-full.jar as workaround. we will fix
this logging problem before next release.
