[debug] ( javajni.c:195 ) Invalid RuntimeLib should be a warning or error?
So, I’ll file a bug about this, but I wanted to get a general feel from the
list first. This happens in both Tomcat 6 and 7 (haven’t looked at 5.5),
but I’ve only included the Tomcat 7 log info here for succinctness.
When running Tomcat as a service under Windows, if you mess up the Java
Virtual Machine path in the service configurator, it defaults to the
JAVA_HOME JRE, which I suppose is okay (but can wreak havoc when you have
multiple Java versions installed), except that it doesn’t warn you about
it. It tells you about it through a DEBUG message, instead, so you have to
actually increase the logging detail and wade through more messages to find
it:

After correcting the JVM path:

IMO, this message should be a warning or even an error (preferable) so that
server admins know right off the bat that they’ve done something wrong.
Thoughts?

The service wrapper is not part of Tomcat project.
It is "procrun" from Apache Commons Daemon. If you want to file an
issue, you should do it there.
http://commons.apache.org/daemon/

That is a general Commons Daemon issue rather than a Tomcat specific issue
and would be best discussed over on the Commons lists.
