Can't be that specifically, since the CLASSPATH environment variable
isn't used by the JVM proper, just the launcher in the absence of the
-cp parameter.  Probably not any other environment variables, since
(AFAIK) Tomcat's classloaders don't look at any.  However, it might be
interesting to compare the system properties visible to Tomcat after a
reboot with those after a Tomcat restart.  The LambdaProbe add-on can
display them, for example.  Turning on -verbose:class might also provide
some hints, but it will produce a lot of output.
