[Bug libgcj/29869] New: LogManager class loading failure with Tomcat

[marcus at better dot se]

I'm trying to run Tomcat 5.5 with gij. It tries to load a log manager through
the java.util.logging.manager property. Apparently the class loading code in
java.util.logging.LogManager fails to load the correct class, even though it is
on the classpath. The exact same invocation with Sun JDK works correctly.

$ /usr/lib/jvm/java-gcj/bin/java
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=/home/marcus/apache-tomcat-5.5.20/conf/logging.properties

This is with a Tomcat 5.5.20 binary distribution from http://tomcat.apache.org,
and gij on Debian i386:

A workaround is to disable the java.util.logging.manager property. Tomcat
appears to run correctly then.

I can confirm the bug with CACAO and current CVS head.

A stack trace would help here ... can you install debug info or something
and try again?

[Bug libgcj/29869] LogManager class loading failure with Tomcat

[tromey at gcc dot gnu dot org]

------- Comment #4 from tromey at gcc dot gnu dot org  2007-03-29 17:48 -------
I suspect we're trying to initialize the logging manager too early.
In particular in libgcj we use 'null' as the loader parameter to
Class.forName during startup -- this will bypass the system class loader.

Second, JarUtils using a logger?  That seems weird.  At least it should
only do that lazily...

Third, what's up with the class name "1catalina.org.apache.juli.FileHandler,"?
Perhaps we are not parsing something correctly?

It comes from a configuration file for the logging mechanism,
/var/lib/tomcat5.5/conf/logging.properties:

handlers = 1catalina.org.apache.juli.FileHandler,
2localhost.org.apache.juli.FileHandler, 3
manager.org.apache.juli.FileHandler, 4admin.org.apache.juli.FileHandler,
5host-manager.org.
apache.juli.FileHandler, java.util.logging.ConsoleHandler

.handlers = 1catalina.org.apache.juli.FileHandler,
java.util.logging.ConsoleHandler

############################################################
# Handler specific properties.
# Describes specific configuration info for Handlers.
############################################################

1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs

2localhost.org.apache.juli.FileHandler.level = FINE
2localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
2localhost.org.apache.juli.FileHandler.prefix = localhost.

------- Comment #6 from tromey at gcc dot gnu dot org  2007-03-29 18:43 -------
Thanks.

This is a little bit screwy since Java 5 claims that 'handlers' is
whitespace-separated -- but I see that in Java 6 they updated the
docs to reflect the actual implementation.

Also tomcat seems to rely on the implementation ignoring classes it
can't find.  And, tomcat extends the meaning of this field; see the
JULI configuration stuff here:

http://tomcat.apache.org/tomcat-5.5-doc/logging.html

That's sort of gross :(
Anyway, working on a patch now.
