Is this the cause of the error? I see that
org/apache/commons/logging/LogFactory is used in a couple places, but in my
case it consistently throws the exception in AprImpl.class.
Details for my config, if they're relevant:
OS: Solaris 8 UltraSPARC
Java: J2SDK1.4.1
Jakarta-Tomcat: 5.0.0
Apache: 2.0.40

: Answering my own mail, it seems Log is loaded twice, once
: during init ( and it may be related with my setup, as I have
: few log uses in the startup code ), and then it is loaded
: again from the webapp loader, but this time it's a different
: instance ( due to reverse order ). And somehow the check for
: assignment happens with the original Log instance.
:
: If this is correct - we can either make commons-logging(-api) a
: special case, or make sure it is not used in any code from
: the common loader ( the use from the container loader should
: be ok ).
:
: I love ClassLoaders :-)
