[debug] ( javajni.c:195 ) Invalid RuntimeLib should be a warning or error?
--------------------------------------------------------------------------
Key: DAEMON-247
URL: https://issues.apache.org/jira/browse/DAEMON-247
Project: Commons Daemon
Issue Type: Bug
Components: Procrun
Affects Versions: 1.0.9
Environment: Windows Server 2008 Service Pack 2, Java 6 update 31 and
7 update 3 installed on same machine.
Tomcat 7.0.26 (which uses Daemon 1.0.9).
Reporter: Nick Williams
When running Tomcat as a service under Windows (thus using Daemon/procrun), 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
even realize it happened:

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.
Otherwise bad things might happen.
Whether or not it should quit instead of defaulting to the system default JRE
is a different discussion, but I think the message should at least be changed
to a warning or an error.
