Hello,
when I try to start Tomcat 7.0.42 with OpenJDK 6 b27, it complains about
not finding classes for the logging handlers. I created a minimal
logging.properties to narrow down the problem:
handlers = 1catalina.org.apache.juli.FileHandler,
java.util.logging.ConsoleHandler
.handlers = java.util.logging.ConsoleHandler
1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.FileHandler.prefix = catalinatest.
java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter =
java.util.logging.SimpleFormatter
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers =
1catalina.org.apache.juli.FileHandler
The output of "./catalina.sh run" is the following:
INFO: Starting Servlet Engine: Apache Tomcat/7.0.42
Can't load log handler "1catalina.org.apache.juli.FileHandler"
java.lang.ClassNotFoundException: 1catalina.org.apache.juli.FileHandler

There can be found many mentions on this topic on the web, each of them
proposing one of those solutions which I tried:
* Check/set JAVA_HOME / JRE_HOME
$ export JAVA_HOME=/usr/local/openjdk6/
$ export JRE_HOME=/usr/local/openjdk6/jre/
* Check/set CATALINA_HOME
$ export
CATALINA_HOME=/home/mpeterma/System/Apps/apache-tomcat-7.0.42
* Ensure LOGGING_CONFIG and LOGGING_MANAGER are set properly
--> validated, LOGGING_MANAGER is set to
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager in
catalina.sh if unspecified, which should be correct; LOGGING_CONFIG is
found because it contains the handlers where Tomcat complains about
* Ensure tomcat-juli.jar is in the classpath
--> validated, it's using
/home/mpeterma/System/Apps/apache-tomcat-7.0.42/bin/bootstrap.jar:/home/mpeterma/System/Apps/apache-tomcat-7.0.42/bin/tomcat-juli.jar
* Place tomcat-juli.jar into Tomcat lib folder --> tested, unsuccessful
* Place tomcat-juli.jar into OpenJDK / JRE lib folder(s) --> tested,
unsuccessful
None of this proposals fixed the problem for me. When I comment out the
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].* -lines
from logging.properties, the problem disappears. Anyway - this is not a
solution as the logging is not working then.
The only workaround which *is* working is to use OpenJDK 7 instead of
OpenJDK 6. But I would like to make it run on OpenJDK 6.
$ java -version
openjdk version "1.6.0_32"
OpenJDK Runtime Environment (build 1.6.0_32-b27)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)
Is there a known problem with this JDK or with OpenJDK in general? It
might be noteworty that I have this problem on FreeBSD only. The Linux
version of OpenJDK 6 b27 (reports as IcedTea6 / OpenJDK 6 b27) works.
There was a bug report filed against the FreeBSD OpenJDK 6 port already:
http://www.freebsd.org/cgi/query-pr.cgi?pr=177067&cat=
At this time it is not clear to me where to look for the root cause. I
appreciate your help and hints, looking for directions where to
investigate in detail.
Kind regards,
Matthias
